Allow format to be an object to generate JSON logs. The object keys
become JSON field names, and values support string, variable, and JS.
Note that when there is no JS in the format values, the object will
be pre-serialized to a JSON template string at configuration phase
for better performance.
Example config:
{
"access_log": {
"path": "/tmp/access.log",
"format": {
"remote_addr": "$remote_addr",
"time_local": "$time_local",
"request_line": "$request_line",
"status": "$status",
"body_bytes_sent": "$body_bytes_sent",
"header_referer": "$header_referer",
"header_user_agent": "$header_user_agent"
}
}
}
|
|
This is a preparatory refactoring for upcoming JSON format support
in access log. We will extend format option to access object for
JSON support.
No functional changes.

When configuring under Linux we always got the following
checking for pthread spinlock zero initial value ... found but is not working
Having *actually* taken a look at this, this check seems somewhat bogus,
the first thing it does is
pthread_spinlock_t lock = 0;
which you shouldn't do anyway, you should use pthread_spin_init(3) to
initialise the pthread_spinlock_t variable.
But in any case, this thing, NXT_HAVE_PTHREAD_SPINLOCK_ZERO, isn't even
checked for in the code.
Neither is NXT_HAVE_PTHREAD_SPINLOCK, we don't use the pthread_spin_*
API, but rather roll our own spinlock implementation.
So let's just remove these checks, at the very least it'll speed
./configure up!

This does compile-time type and argument checking using a clang-plugin.
It was run as part of buildbot.
This covers unitd, src/test and the php, perl, python, ruby, wasm, java
and nodejs language modules/support.
It doesn't cover Go as that doesn't build anything with clang (uses
cgo) or wasm-wasi-component as that uses rustc.

sizeof() should never be used to get the size of an array. It is
very unsafe, since arrays easily decay to pointers, and sizeof()
applied to a pointer gives false results that compile and produce
silent bugs.
It's better to use nxt_items(), which implements sizeof()
division, which recent compilers warn when used with pointers.
This change would have caught a couple of bugs that were *almost*
introduced
First up is the _infamous_ ternary macro bug (yes, using the ternary
operator in a macro is of itself a bad idea)
nxt_str_set(&port, (r->tls ? "https://" : "http://"));
which in the macro expansion runs:
(&port)->length = nxt_length((r->tls ? : "https://" : "http://"));
which evaluates to:
port.length = sizeof(r->tls ? "https://" : "http://") - 1;
which evaluates to:
port.length = 8 - 1;
Of course, we didn't want a compile-time-constant 8 there, but
rather the length of the string.
The above bug is not obvious to the untrained eye, so let's show some
example programs that may give some more hints about the problem.
$ cat sizeof.c
#include <stdio.h>
int
main(void)
{
printf("%zu\n", sizeof("01"));
printf("%zu\n", sizeof("012"));
printf("%zu\n", sizeof(char *));
}
$ cc -Wall -Wextra sizeof.c
$ ./a.out
3
4
8
sizeof() returns the size in bytes of the array passed to it, which in
case of char strings, it is equivalent to the length of the string + 1
(for the terminating '\0').
However, arrays decay very easily in C, and they decay to a pointer to
the first element in the array. In case of strings, that is a 'char *'.
When sizeof() is given a pointer, it returns the size of the pointer,
which in most platforms is 8.
The ternary operator (?) performs default promotions (and other
nefarious stuff) that may surprise even the most experienced
programmers. It contrasts the __builtin_choose_expr() GCC builtin [1],
which performs almost equivalently, but without the unwanted effects of
the ternary operator.
[1]: <https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html#index-_005f_005fbuiltin_005fchoose_005fexpr>
$ cat ?.c
#include <stdio.h>
int
main(void)
{
printf("%zu\n", sizeof("01"));
printf("%zu\n", sizeof(__builtin_choose_expr(1, "01", "01")));
printf("%zu\n", sizeof(1 ? "01" : "01"));
printf("%zu\n", sizeof(char *));
}
$ cc -Wall -Wextra ?.c
$ ./a.out
3
3
8
8
In the above program, we can see how the ternary operator (?) decays
the array into a pointer, and makes it so that sizeof() will return a
constant 8.
As we can see, everything in the use of the macro would make it look
like it should work, but the combination of some seemingly-safe side
effects of various C features produces a completely unexpected bug.
Second up is a more straight forward case of simply calling nxt_length()
on a char * pointer.
Like the above this will generally result in a length of 7.
When you sit and think about it, you know very well sizeof(char *) is
probably 8 these days (but may be some other value like 4).
But when you're in the depths of code it's very easy to overlook this
when all you're thinking about is to get the length of some string.
Let's look at this patch in action
$ cat sdiv.c
#include <stdio.h>
#define nxt_nitems(x) (sizeof(x) / sizeof((x)[0]))
#define nxt_length(s) (nxt_nitems(s) - 1)
#define nxt_unsafe_length(s) (sizeof(s) - 1)
#define STR_LITERAL "1234567890"
static const char *str_lit = "1234567890";
int main(void)
{
printf("[STR_LITERAL] nxt_unsafe_length(\"1234567890\") [%lu]\n",
nxt_unsafe_length(STR_LITERAL));
printf("[STR_LITERAL] nxt_length(\"1234567890\") [%lu]\n",
nxt_length(STR_LITERAL));
printf("[char * ] nxt_unsafe_length(\"1234567890\") [%lu]\n",
nxt_unsafe_length(str_lit));
printf("[char * ] nxt_length(\"1234567890\") [%lu]\n",
nxt_length(str_lit));
return 0;
}
First lets compile it without any flags
$ make sdiv
$ ./sdiv
[STR_LITERAL] nxt_unsafe_length("1234567890") [10]
[STR_LITERAL] nxt_length("1234567890") [10]
[char * ] nxt_unsafe_length("1234567890") [7]
[char * ] nxt_length("1234567890") [7]
It compiled without error and runs, although with incorrect results for
the two char *'s.
Now lets build it with -Wsizeof-pointer-div (also enabled with -Wall)
$ CFLAGS="-Wsizeof-pointer-div" make sdiv
cc -Wsizeof-pointer-div nxt_nitems.c -o nxt_nitems
sdiv.c: In function ‘main’:
sdiv.c:3:44: warning: division ‘sizeof (const char *) / sizeof (char)’ does not compute the number of array elements [-Wsizeof-pointer-div]
3 | #define nxt_nitems(x) (sizeof(x) / sizeof((x)[0]))
| ^
nxt_nitems.c:4:34: note: in expansion of macro ‘nxt_nitems’
4 | #define nxt_length(s) (nxt_nitems(s) - 1)
| ^~~~~~~~~~

| ^~~~~~~~~~
nxt_nitems.c:10:20: note: first ‘sizeof’ operand was declared here
10 | static const char *str_lit = "1234567890";
| ^~~~~~~
So we now get a very loud compiler warning (coming from nxt_length(char
*), nxt_unsafe_length() of course didn't trigger any warnings), telling
us we're being daft.
The good news is this didn't find any existing bugs! Let's keep it that
way...

In the perl language module we create a new perl *module* on the fly
comprised of some preamble, the specified perl script and some
post-amble.
In the preamble we create a constructor called new(), however this can
clash with other constructors also called new.
While this can be worked around by instead of doing
... new CLASS
rather do
... CLASS->new()
While this constructor was added in commit 3b2c1d0e ("Perl: added
implementation delayed response and streaming body."), I don't see that
we actually use it anywhere (nor is it seemingly something we document)
and if we simply remove it then things still seem to work, including the

Under Ubuntu 24.04 the pytest for
test/test_php_isolation.py::test_php_isolation_rootfs fails due to Unit
aborting (SIGABRT) in the PHP language module due to FORIFY_SOURCE
hardening detecting a buffer overflow
2024/10/16 16:46:54 [info] 11661#11661 "phpinfo" application started
*** buffer overflow detected ***: terminated
2024/10/16 16:46:54 [alert] 11660#11660 app process 11661 exited on signal 6
After spending an extraordinary amount of time faffing around with
Ubuntu and pytests (they don't make for a pleasant combination) I was
able to reproduce it.
The crash was occurring here
#4 0x00007ebe818288ff in __GI_abort () at ./stdlib/abort.c:79

#11 0x00007ebe812e0885 in zm_info_date (zend_module=0x571ba9a14420)
[Well as best as I can tell, as this is from the php 8.1 packages from
<https://github.com/oerdnj/deb.sury.org>, I don't know where the
packages (I'm assuming it's packages) shivammathur/setup-php@v2
installs come from.]
So we get killed in fake_data_segment(), the thing is, that function (as
well as timelib_builtin_db()) doesn't exist in upstream PHP.
It turns out these come from a patch that is applied by distributions to
make PHP use the system installed timezone database rather than the one
built into PHP.
I was unable to reproduce this with vanilla PHP 8.1.
It can be triggered on affected builds with the following config
{
"listeners": {
"[::1]:8080": {
"pass": "applications/php"
}
},
"applications": {
"php": {
"type": "php",
"root": "/app/php",
"isolation": {
"rootfs": "/tmp/unit-root",
"namespaces": {
"mount": true,
"credential": true,
"pid": true
}
}
}
}
}
The crux of the issue seems to come down to in this case PHP can't open
the tz database as it's not contained in the new mount namespace.
190437 openat(AT_FDCWD, "/usr/share/zoneinfo/", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = -1 ENOENT (No such file or directory)
190437 openat(AT_FDCWD, "/usr/share/zoneinfo/zone.tab", O_RDONLY) = -1 ENOENT (No such file or directory)
190437 writev(2, [{iov_base="*** ", iov_len=4}, {iov_base="buffer overflow detected", iov_len=24}, {iov_base=" ***: terminated\n", iov_len=17}], 3) = 45
...
190437 --- SIGABRT {si_signo=SIGABRT, si_code=SI_TKILL, si_pid=2, si_uid=65534} ---
190437 +++ killed by SIGABRT +++
Specifically the issue is with the following code in the patch
(certainly an earlier version of the patch, this is from a Debian patch
<https://sources.debian.org/src/php8.2/8.2.20-1~deb12u1/debian/patches/0007-Add-support-for-use-of-the-system-timezone-database.patch/>)
+ data = malloc(3 * sysdb->index_size + 7);
+
+ p = mempcpy(data, FAKE_HEADER, sizeof(FAKE_HEADER) - 1);
If the zone file hasn't been found then sysdb->index_size is 0. So we
malloc(3) a total of 7 bytes.
However, sizeof(FAKE_HEADER) - 1 is 10. (Hence the __len=10 in the
mempcpy(3) in the above backtrace).
Of course 10 doesn't fit into 7 and the FORTIFY_SOURCE hardening kicks
in and SIGABRTs the process.
Now, it's worth noting that this issue doesn't occur with PHP 8.2 and
8.3.
As can been seen from the Fedora patch for this
<https://src.fedoraproject.org/rpms/php/blob/rawhide/f/php-8.4.0-systzdata-v24.patch>
They actually have a fix incorporated
r23: fix possible buffer overflow
So the above patch now does
+ data = malloc(3 * sysdb->index_size + sizeof(FAKE_HEADER) - 1);
+
+ p = mempcpy(data, FAKE_HEADER, sizeof(FAKE_HEADER) - 1);
So you will always get at least the required 10 bytes allocated.
I assume the PHP 8.2 & 8.3 packages either no longer use this patch or
have the fixed version. I don't know... I haven't found the sources...
Anyway the above was more about satisfying myself that the problem
wasn't with Unit.
PHP 8.1 is now in security maintenance mode and people are actively
encouraged to upgrade to 8.2/8.3
So lets just remove 8.1 from our testing...
[It's also worth noting that after all this, the ubuntu-latest runners
seemed to have switched back from 24.04 to 22.04. However lets stick
with this and the other ci fixes as who knows when it'll go back to
24.04 (or some other version) again...]

There has been a long standing clang-analyzer issue in
nxt_process_check_pid_status(), well ever since I introduced this
function in commit b0e2d9d0a ("Isolation: Switch to fork(2) & unshare(2)
on Linux."),
It is complaining that there are cases where 'status' could be returned
with an undefined or garbage value.
Now I'm convinced this can't happen
If nxt_process_pipe_timer() returns NXT_OK
read(2) the status value
If the read(2) failed or if we got NXT_ERROR from
nxt_process_pipe_timer(), NXT_OK (0) and NXT_ERROR (-1) are the only
possible return values here, then we set status to -1
I don't see a scenario where status is either not set by the read(2) or
not set to -1.
Now I'm not a fan of initialising variables willy-nilly, however, in
this case if we initialise status to -1, then we can simply remove the
if (ret <= 0) {
check. So it closes this (non-)issue but also provides a little code
simplification.
NOTE: There is no need to check the return from the read(2) here. We are
reading a single byte, we either get it or don't.

Both clang-analyzer and coverity flagged an issue in nxt_term_parse()
that we set 'state = st_letter' but then set it to 'state = st_space'
before using it.
While we could simply remove the first assignment and placate the
analyzers, upon further analysis it seems that there is some more
cleanup that could be done in this function.
This commit addresses the above issue, subsequent commits will continue
the cleanup.
To solve the unused assignment issue we can get rid of the
'state == st_letter'
assignment and unconditionally execute the code that was behind the
if (state != st_letter) {
guard. If we're not handling a space then we should have either a digit
or letter.
Also, perhaps more importantly, this if () statement would never be
false at this point as state would never == st_letter.
We may as well also remove the st_letter enum value.
The src/test/nxt_term_parse_test.c still passes
tests: [notice] term parse test passed
NOTE: Although this function is not currently used in Unit (only by
src/test/nxt_term_parse_test.c), it is probably worth cleaning it up and
solving one of the open clang-analyzer (and coverity) issues.

Due to 'char' (unless explicitly set) being signed or unsigned depending
on architecture, e.g on x86 it's signed, while on Arm it's unsigned,
this can lead to subtle bugs such if you use a plain char as a byte
thinking it's unsigned on all platforms (maybe you live in the world of
Arm).
What we can do is tell the compiler to treat 'char' as unsigned by
default, thus it will be consistent across platforms. Seeing as most of
the time it doesn't matter whether char is signed or unsigned, it
really only matters when you're dealing with 'bytes', which means it
makes sense to default char to unsigned.
The Linux Kernel made this change at the end of 2022.
This will also allow in the future to convert our u_char's to char's
(which will now be unsigned) and pass them directly into the libc
functions for example, without the need for casting.
Here is what the ISO C standard has to say
From §6.2.5 Types ¶15
The three types char, signed char, and unsigned char are collectively
called the character types. The implementation shall define char to
have the same range, representation, and behavior as either signed
char or unsigned char.[45]
and from Footnote 45)
CHAR_MIN, defined in <limits.h>, will have one of the values 0 or
SCHAR_MIN, and this can be used to distinguish the two options.
Irrespective of the choice made, char is a separate type from the
other two and is not compatible with either.
If you're still unsure why you'd want this change...
It was never clear to me, why we used u_char, perhaps that was used as
an alternative to -funsigned-char...
But that still leaves the potential for bugs with char being unsigned vs
signed...
Then because we use u_char but often need to pass such things into libc
(and perhaps other functions) which normally take a 'char' we need to
cast these cases.
So this change brings at least two (or more) benefits
1) Removal of potential for char unsigned vs signed bugs.
2) Removal of a bunch of casts. Reducing casting to the bare minimum
is good. This helps the compiler to do proper type checking.
3) Readability/maintainability, everything is now just char...
What if you want to work with bytes?
Well with char being unsigned (everywhere) you can of course use char.
However it would be much better to use the uint8_t type for that to
clearly signify that intention.

All new NGINX projects are created from the template repository which
has a SECURITY.md file in it. This adopts the file.
NOTE; We wrap the file around the 76-78 character mark for consistency
and readability.

On some Python 3.11 systems, 3.11.9 & 3.11.10, we were seeing a crash
triggered by Py_Finalize() in nxt_python_atexit() when running one of
our pytests, namely
test/test_python_factory.py::test_python_factory_invalid_callable_value
2024/09/12 15:07:29 [alert] 5452#5452 factory "wsgi_invalid_callable" in module "wsgi" can not be called to fetch callable
Fatal Python error: none_dealloc: deallocating None: bug likely caused by a refcount error in a C extension
Python runtime state: finalizing (tstate=0x00007f560b88a718)
Current thread 0x00007f560bde7ad0 (most recent call first):
<no Python frame>
2024/09/12 15:07:29 [alert] 5451#5451 app process 5452 exited on signal 6 (core dumped)
This was due to
obj = PyDict_GetItemString(PyModule_GetDict(module), callable);
in nxt_python_set_target() which returns a *borrowed* reference, then
due to the test meaning this is a `None` object we `goto fail` and call
Py_DECREF(obj);
which then causes `Py_Finalize()` to blow up.
The simple fix is to just increment its reference count before the `goto
fail`.
Note: This problem only showed up under (the various versions of Python
we test on); 3.11.9 & 3.11.10. It doesn't show up under; 3.6, 3.7, 3.9,
3.10, 3.12

When the client closes the connection before the upstream,
the proxy's error handler was calling cleanup operation like
peer close and request close twice, this fix ensures the cleanup
is performed only once, improving proxy stability.

Suppress the output from cargo-component when we first run it to check
if it's available, otherwise you may see the following
$ pytest test/test_wasm-wasi-component.py
which: no go in (/home/andrew/.local/bin:/home/andrew/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin)
error: no such command: `component`
View all installed commands with `cargo --list`
Find a package to install `component` with `cargo search cargo-component
Note: This didn't stop the tests from working, just an aesthetic issue.
