Subject: [PATCH] bpftool: Mount bpffs on provided dir instead of parent dir
|
|
||||||
|
|
||||||
When pinning programs/objects under PATH (eg: during "bpftool prog
|
|
||||||
loadall") the bpffs is mounted on the parent dir of PATH in the
|
|
||||||
following situations:
|
|
||||||
- the given dir exists but it is not bpffs.
|
|
||||||
- the given dir doesn't exist and the parent dir is not bpffs.
|
|
||||||
|
|
||||||
Mounting on the parent dir can also have the unintentional side-
|
|
||||||
effect of hiding other files located under the parent dir.
|
|
||||||
|
|
||||||
If the given dir exists but is not bpffs, then the bpffs should
|
|
||||||
be mounted on the given dir and not its parent dir.
|
|
||||||
|
|
||||||
Similarly, if the given dir doesn't exist and its parent dir is not
|
|
||||||
bpffs, then the given dir should be created and the bpffs should be
|
|
||||||
mounted on this new dir.
|
|
||||||
|
|
||||||
Fixes: 2a36c26fe3b8 ("bpftool: Support bpffs mountpoint as pin path for prog loadall")

|
|
||||||
|
|
||||||
Closes: https://github.com/libbpf/bpftool/issues/100
|
|
||||||
|
|
||||||
Changes since v1:
|
|
||||||
- Split "mount_bpffs_for_pin" into two functions.
|
|
||||||
This is done to improve maintainability and readability.
|
|
||||||
|
|
||||||
Changes since v2:
|
|
||||||
- mount_bpffs_for_pin: rename to "create_and_mount_bpffs_dir".
|
|
||||||
- mount_bpffs_given_file: rename to "mount_bpffs_given_file".
|
|
||||||
- create_and_mount_bpffs_dir:
|
|
||||||
- introduce "dir_exists" boolean.
|
|
||||||
- remove new dir if "mnt_fs" fails.
|
|
||||||
- improve error handling and error messages.
|
|
||||||
|
|
||||||
Changes since v3:
|
|
||||||
- Rectify function name.
|
|
||||||
- Improve error messages and formatting.
|
|
||||||
- mount_bpffs_for_file:
|
|
||||||
- Check if dir exists before block_mount check.
|
|
||||||
|
|
||||||
Changes since v4:
|
|
||||||
- Use strdup instead of strcpy.
|
|
||||||
- create_and_mount_bpffs_dir:
|
|
||||||
- Use S_IRWXU instead of 0700.
|
|
||||||
- Improve error handling and formatting.

If a value is assigned to the variable DESTDIR when compiling bpftool,

this variable will be passed to libbpf's Makefile.
|
|

|
|
||||||
In this case, libbpf's header files will be installed in an unexpected

Subject: [PATCH] bpftool: Fix undefined behavior in qsort(NULL, 0, ...)
|
|
||||||
|
|
||||||
When netfilter has no entry to display, qsort is called with
|
|
||||||
qsort(NULL, 0, ...). This results in undefined behavior, as UBSan
|
|
||||||
reports:
|
|
||||||
|
|
||||||
net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null
|
|
||||||
|
|
||||||
Although the C standard does not explicitly state whether calling qsort
|
|
||||||
with a NULL pointer when the size is 0 constitutes undefined behavior,
|
|
||||||
Section 7.1.4 of the C standard (Use of library functions) mentions:
|
|
||||||
|
|
||||||
"Each of the following statements applies unless explicitly stated
|
|
||||||
otherwise in the detailed descriptions that follow: If an argument to a
|
|
||||||
function has an invalid value (such as a value outside the domain of
|
|
||||||
the function, or a pointer outside the address space of the program, or
|
|
||||||
a null pointer, or a pointer to non-modifiable storage when the
|
|
||||||
corresponding parameter is not const-qualified) or a type (after
|
|
||||||
promotion) not expected by a function with variable number of
|
|
||||||
arguments, the behavior is undefined."
|
|
||||||
|
|
||||||
To avoid this, add an early return when nf_link_info is NULL to prevent
|
|
||||||
calling qsort with a NULL pointer.

Subject: [PATCH] mirror: Define PACKAGE at build time when trying to detect libbfd
|
|
||||||
|
|
||||||
Feature detection from the Makefile.feature for libbfd (with the
|
|
||||||
different variants of the probe) may fail on some systems where the
|
|
||||||
bfd.h and dis-asm.h headers expect the PACKAGE or PACKAGE_VERSION macros
|
|
||||||
to be defined [0]. In the kernel tree, feature detection addresses it by
|
|
||||||
defining the PACKAGE macro when invoking the compiler [1]. Add a similar
|
|
||||||
definition for the mirror repository.
|
|
||||||
|
|
||||||
Note that this issue has remained undetected for a while. This is
|
|
||||||
because the bfd.h included in some distributions (Debian/Ubuntu, for
|
|
||||||
example) does not contain the inclusion guard [2].

Subject: [PATCH] mirror: Always disable unused CLI arguments warning for feature probe
|
|
||||||
|
|
||||||
In commit 8a2d7d510ccd ("mirror: Fix features detection for building
|
|
||||||
with clang") we prevented clang to error out when encountering unused
|
|
||||||
command-line arguments in the feature probes, because we do add unused
|
|
||||||
arguments for some of the probes when retrieving arguments from
|
|
||||||
llvm-config, and we don't want probes to fail because of that.
|
|
||||||
|
|
||||||
At the time, the issue was apparent for the LLVM-based disassembler, so
|
|
||||||
we added -Wno-unused-command-line-argument when $(LLVM) was enabled,
|
|
||||||
only. We missed the case when we're building bpftool with clang instead
|
|
||||||
of gcc, without building the LLVM disassembler. Let's disable the
|
|
||||||
warning unconditionally instead to fix this case.

Subject: bpf: bpftool: Setting error code in do_loader()
|
||||||
|
|
||||||
|
From: Sewon Nam <swnam0729@gmail.com>
|

[ Upstream commit 02a4694107b4c830d4bd6d194e98b3ac0bc86f29 ]
|
||||||
|
|
||||||
|
We are missing setting error code in do_loader() when
|
||||||
|
bpf_object__open_file() fails. This means the command's exit status code
|
||||||
|
will be successful, even though the operation failed. So make sure to
|
||||||
|
return the correct error code. To maintain consistency with other
|
||||||
|
locations where bpf_object__open_file() is called, return -1.
|
||||||
|
|
||||||
