Subject: [PATCH 1/2] depmod: prevent module dependency files missing during
|
||||
depmod invocation
|
||||
|
||||
depmod deletes the module dependency files before moving the temporary
|
||||
files in their place. This results in user seeing no dependency files
|
||||
while they are updated. Remove the unlink call. The rename call should
|
||||
suffice to move the new file in place and unlink the old one. It should
|
||||
also do both atomically so there is no window when no dependency file
|
||||
exists.

Subject: [PATCH] libkmod: avoid undefined behaviour in
|
||||
libkmod-builtin.c:get_string
|
||||
|
||||
Static analysis has reported a potential UB:
|
||||
|
||||
kmod-31/libkmod/libkmod-builtin.c:125: use_invalid: Using "nullp", which points to an out-of-scope variable "buf".
|
||||
# 123| size_t linesz = 0;
|
||||
# 124|
|
||||
# 125|-> while (!nullp) {
|
||||
# 126| char buf[BUFSIZ];
|
||||
# 127| ssize_t sz;
|
||||
|
||||
It seems to be indeed an UB, as nullp is getting assined an address
|
||||
inside object buf, which has a lifetime of the while loop body,
|
||||
and is not available outside of it (specifically, in the while
|
||||
condition, where nullp is checked for NULL). Fix it by putting
|
||||
buf definition in the outer block.

Currently if we see unknown algorithm, we'll do an OOB read in

pkey_hash_algo. This can happen for example if OPENSSL_NO_SM3 is set and
|

the kernel module uses a SM3 hash.

Subject: [PATCH 2/2] depmod: prevent module dependency files corruption due to
|
||||
parallel invocation.
|
||||
|
||||
Depmod does not use unique filename for temporary files. There is no
|
||||
guarantee the user does not attempt to run mutiple depmod processes in
|
||||
parallel. If that happens a temporary file might be created by
|
||||
depmod(1st), truncated by depmod(2nd), and renamed to final name by
|
||||
depmod(1st) resulting in corrupted file seen by user.
|
||||
|
||||
Due to missing mkstempat() this is more complex than it should be.
|
||||
Adding PID and timestamp to the filename should be reasonably reliable.
|
||||
Adding O_EXCL as mkstemp does fails creating the file rather than
|
||||
corrupting existing file.

Subject: [PATCH] libkmod-signature: implement pkcs7 parsing with openssl
|
||||
|
||||
The patch adds data fetching from the PKCS#7 certificate using
|
||||
openssl library (which is used by scripts/sign-file.c in the linux
|
||||
kernel to sign modules).
|
||||
|
||||
In general the certificate can contain many signatures, but since
|
||||
kmod (modinfo) supports only one signature at the moment, only first
|
||||
one is taken.
|
||||
|
||||
With the current sign-file.c certificate doesn't contain signer
|
||||
key's fingerprint, so "serial number" is used for the key id.

Subject: [PATCH] modprobe: ignore builtin module on recursive removing
|
||||
|
||||
If there are built-in dependencies and any of them is built-in in
|
||||
the kernel, modprobe -r fails with
|
||||
|
||||
modprobe: FATAL: Module module_name is builtin.
|
||||
|
||||
It makes sense to ignore such dependencies for the case when
|
||||
removing is called for non-top level module.
|
||||
|
||||
Example: cifs module, it declares bunch of softdeps and the first
|
||||
one fails on some kernel configs:
|
||||
|
||||
modprobe: FATAL: Module gcm is builtin.

Subject: [PATCH] signature: do not report wrong data for pkc#7 signature
|
||||
|
||||
when PKC#7 signing method is used the old structure doesn't contain
|
||||
any useful data, but the data are encoded in the certificate.
|
||||
|
||||
The info getting/showing code is not aware of that at the moment and
|
||||
since 0 is a valid constant, shows, for example, wrong "md4" for the
|
||||
hash algo.
|
||||
|
||||
The patch splits the 2 mothods of gethering the info and reports
|
||||
"unknown" for the algo.
