We can't do at configure phase since we actually ship the built man pages with
dist, so it's fine not having xsltproc if building from dist. If building from
the repository, it's better to have have a better message saying xsltproc was
not found than trying to execute the argument to xsltproc. Now message is:
XSLT depmod.d.5
/bin/sh: line 1: xsltproc: command not found
Instead of:
XSLT depmod.d.5
/bin/sh: --nonet: command not found

Fix failing distcheck
|

This is a rework of depmod report cycles logic to make it
tolerant to more complex loops.
The patch tries to remember own path for vertexes which makes it
possible to handle configurations with common edges and
non-cyclic modules.
It assumes that the previous dependency calculations can not give
as input something like
mod_a -> mod_b -> <loop>, but
<loop> -> mod_a -> mod_b should be fine.

The patch adds nested loops configuration for the loop test:
mod-loop-h -> mod-loop-i -> mod-loop-j -> mod-loop-k
^ | |
--------------------------- |
| |
-------------------------------------------
making 2 loops with common edges:
mod-loop-h -> mod-loop-i -> mod-loop-j -> mod-loop-h
mod-loop-h -> mod-loop-i -> mod-loop-j -> mod-loop-k -> mod-loop-h
The actual output for the loops is:
depmod: ERROR: Cycle detected: mod_loop_h -> mod_loop_h
depmod: ERROR: Cycle detected: mod_loop_i -> mod_loop_j -> mod_loop_k -> mod_loop_h -> mod_loop_i
(the order in the second doesn't matter, but the first one is
incorrect)

We can only accept quoted values, not module names or parameter names.
|
|
|
|
When a module is removed and re-inserted without unrefing, the
kmod_file is unconditionally re-opened. This results in a memory
and file descriptor leak.
Fix it by checking if the file is already open in
kmod_module_insert_module().

Add some tests in which we quotes in kernel cmdline and also spaces
inside quotes. This doesn't yet cover the case in which quotes are used
for module name, wihch should be forbidden.
|
|
|
|
If a module parameter on the command line contains quotes, any
spaces inside those quotes should be included as part of the
parameter.

We need to ship pre-compiled binaries so it's possible to run
"make check" on servers without kernel headers.
Also add them to EXTRA_DIST as other sources.

Only print actual cyclic dependencies. Print count of all the modules
in cyclic dependency at the end of the function so that dependent
modules which are not in cyclic chain can be ignored.
Printing dependent modules which are not in cyclic chain causes buffer
overflow as m->modnamesz is not included in buffer size calculations
(loop == m is never true). This buffer overflow causes kmod to crash.
Update depmod test to reflect the change as well.

Check that depmod do not report modules outside cyclic chain
Two modules f and g are added which do not have any dependency.
modules a and b are made dependent on f and g.
Here is the output of loop dependency check test after adding this
patch:
TESTSUITE: ERR: wrong:
depmod: ERROR: Found 7 modules in dependency cycles!
depmod: ERROR: Cycle detected: mod_loop_d -> mod_loop_e -> mod_loop_d
depmod: ERROR: Cycle detected: mod_loop_b -> mod_loop_c -> mod_loop_a -> mod_loop_b
depmod: ERROR: Cycle detected: mod_loop_b -> mod_loop_c -> mod_loop_a -> mod_loop_g
depmod: ERROR: Cycle detected: mod_loop_b -> mod_loop_c -> mod_loop_a -> mod_loop_f
Buffer overflow occurs in the loop when last two lines are printed.
43 bytes buffer is allocated and 53 bytes are used.

The array elements in the tests are strings, what means "char *"
in С. The comparation funtion takes pointers to the elements, so
the arguments become "char **". It means, that strcmp() cannot be
used directrly.
The patch creates a wrapper on strcmp() which perfoms
dereferencing of the "char **" to supply the actual strings to
strcmp(), and uses the wrapper as a comparation function for the
qsort() call.

Use scratchbuf to fix issue with strcpy that may overflow the buffer we
declared in the stack.
|
|
This should fill the requirements for "we need to loop over a lot of
strings that usually are small enough to remain on stack, but we want to
protect ourselves against huge strings not fitting in the static
buffer we estimated as sufficient"

It's used in the log macros so include it.

shared/util.c: In function ‘read_str_safe’:
shared/util.c:211:24: warning: logical ‘or’ of equal expressions [-Wlogical-op]
if (errno == EAGAIN || errno == EWOULDBLOCK ||
^~
shared/util.c: In function ‘write_str_safe’:
shared/util.c:237:24: warning: logical ‘or’ of equal expressions [-Wlogical-op]
if (errno == EAGAIN || errno == EWOULDBLOCK ||
^~
This is because EAGAIN and EWOULDBLOCK have the same value. Prefer
EAGAIN, but add a static assert to catch if it's not the same in another
architecture.

We were not checking if there was sufficient space in the buffer.

It was failing to generate doc with recent version of gtk-doc
[kmod]$ ./bootstrap
libkmod/docs/gtk-doc.make:33: error: EXTRA_DIST must be set with '=' before using '+='
libkmod/docs/Makefile.am:29: 'libkmod/docs/gtk-doc.make' included from here
autoreconf: automake failed with exit status: 1
Just add an empty EXTRA_DIST so it works.

This way it's possible to give at least the signature type for PKCS#7.

kmod_module_new_from_loaded() calls fgets with a 4k buffer. When a
module such as usbcore is used by too many modules, the rest of the line
is considered a beginning of another lines and we eventually get errors
like these from lsmod:
libkmod: kmod_module_get_holders: could not open '/sys/module/100,/holders': No such file or directory
together with bogus entries in the output. In kmod_module_get_size, the
problem does not affect functionality, but the line numbers in error
messages will be wrong.

The .TOC. symbol on the PowerPC64 ABIv2 identifies the GOT
pointer, similar to how other architectures use _GLOBAL_OFFSET_TABLE_.
This is not a symbol that needs relocation, and should be ignored
by depmod.

Makefile.am uses `sed -E', which it is found on BSD sed; however a
replacement on GNU sed would be `sed -r'. Both intend to use extended
regular expressions (ERE). However I have a system that does not support
those, in benefit for portability could you consider replacing ERE by BRE.

Travis is poluting the environment, particularly PYTHON_CFLAGS which
makes the build to fail. Just unset the variable since we don't want to
override these cflags.
|
|
This allows tools to detect the file as empty, such as via systemd's
ConditionFileNotEmpty.

The -f switch is accepted by insmod, but silently ignored. This
causes the user to wonder why things don't work. As insmod is
most often used with "evil" modules, -f is almost default and
thus needs to work.

Make sure it gets exported and add documentation.

Currently, if a value that doesn't match a kernel version
("%u.%u") is passed in, depmod silently falls back to
using uname. Rather than try and work around the caller passing
bad data, just exit out instead.
