aa-status: fix json output with --count flag 2024-12-09 23:58:04 +01:00

aa-status: fix json generation
- previously, aa-status --json --show profiles would return non-standard json
- adding the --pretty flag would crash completely
- closes #470

Things done:
- removed trailing ", " in json generation
- generate json seperator (", ") for each new json field
  (profiles/processes) after the header if json is enabled

Tested on NixOS and apparmor 4.0.3 base, but should work on any version the patch applies on.

322a98c8c9 Fix incorrect strnlen length in aa_load.c load_policy_dir
POSIX states that d_name has up to NAME_MAX (255) characters, and glibc
stores d_name as an array of size NAME_MAX+1 (256). Thus, supplying
PATH_MAX (4096) as the max length could trigger a buffer overrun. This
could be an even bigger issue on other libcs, as POSIX states that d_name
can be unsized.

Fortunately, this does not seem to cause actual issues, as the length is
only used to compare d_name to a short fixed string. However, it'd be better
to pass the actual correct max length to strnlen.

3ea050eb30 binutils: fix aa-status filters short help message
The short form of the help parameter was not accepting an optional
argument as described in the help message. Update the help message to
remove the extra whitespace in between -h and the options since
getopt(1) says that

"If the option has an optional argument, it must be written directly
after the option character if present."

even though that's not described in getopt(3).

1945ecbf19 aa-status: separate error messages from the regular output
using dfprintf for error messages subjects them to the other
output controls and can cause them to be surpressed when they
shouldn't.

Instead use a dedicated error function and add a quiet flag to
allow silencing errors.

binutils/aa_status.c: quiet verbose outputs when --json is specified
By default aa-status outputs with --verbose enabled - if --json is also
specified then aa-status would currently output in its first line "apparmor
module is loaded.":

aa-status --json | head -n1
apparmor module is loaded.

And only after this the actual json output would follow. This then results in
failures to parse this JSON output:

aa-status --json | jq .
parse error: Invalid numeric literal at line 1, column 9

This in turn then breaks tools / tests which expect the output of aa-status
--json to be purely json - e.g:
https://salsa.debian.org/apparmor-team/apparmor-profiles-extra/-/blob/debian/unstable/debian/tests/policy-is-loaded#L12

So ensure dprintf() etc do not output when --json is specified to restrict the
output of aa-status to pure JSON.

aa-status: Fix malformed json output
In some cases (if profiles in complain and enforce mode are loaded), the
`i` loop runs more than once, which also means `j == 0` is true in the
middle of the json. This causes invalid json.

This patch fixes this.

This is a regression related to 22aa9b6161
/ https://gitlab.com/apparmor/apparmor/-/merge_requests/964 /
https://gitlab.com/apparmor/apparmor/-/issues/295
which fixed another case of invalid json if a process was unconfined
while having a profile defined.

Note: I also tested this patch for the "unconfined, but has a profile
defined" case to ensure it doesn't break what
22aa9b6161 fixed.

457ab38b93 aa-status: fix crash due to \n in profile name
This fixes a crash when a profile name contains a \n character which

the bad profile name and continues processing.

Ideally this name would not exist and is indicative of a bug in the kernel.

binutils/aa-features-abi: fix failure to close fd due to shadowed var decl
The variable used to store the file descriptor for the --file ended up
being declared twice, resulting in the autoclose attribute attached to
the first declaration being removed by the shadowed second declaration.
Fix this by converting the second declaration to just be an assignment,
as was intended.

strace output before:

  [...]
  ) = 1925
  close(1)                                = 0
  exit_group(0)                           = ?
  +++ exited with 0 +++

strace output after removing shadow declaration:

  ) = 1925
  close(1)                                = 0
  close(3)                                = 0
  exit_group(0)                           = ?
  +++ exited with 0 +++

(File descriptor 3 is what is returned by the open() call on the
 --file argument.)

binutils/aa-features-abi: make -f short arg actually be accepted
The aa-features-abi -f short argument was not added to the

  ./aa-features-abi: invalid option -- 'f'
  USAGE: ./aa-features-abi [OPTIONS] <SOURCE> [OUTPUT OPTIONS]

The long --file option works as expected.

getopt_long().
