[PATCH net-next 00/10] netfilter updates for net-next

[Florian Westphal]

Hello,

This batch contains a few updates for your *net-next* tree.
First patch resolves a fortify warning by wrapping the to-be-copied
members via struct_group.

Second patch replaces array[0] with array[] in ebtables uapi.
Both changes from GONG Ruiqi.

The largest chunk is replacement of strncpy with strscpy_pad()
in netfilter, from Justin Stitt.

Last patch, from myself, aborts ruleset validation if a fatal
signal is pending, this speeds up process exit.

The following changes since commit 43c2817225fce05701f062a996255007481935e2:

[PATCH net-next 01/10] netfilter: ebtables: fix fortify warnings in size_entry_mwt()

[Florian Westphal]

From: "GONG, Ruiqi" <gongruiqi1@huawei.com>

When compiling with gcc 13 and CONFIG_FORTIFY_SOURCE=y, the following
warning appears:

In function ‘fortify_memcpy_chk’,
    inlined from ‘size_entry_mwt’ at net/bridge/netfilter/ebtables.c:2118:2:
./include/linux/fortify-string.h:592:25: error: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Werror=attribute-warning]
  592 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The compiler is complaining:

memcpy(&offsets[1], &entry->watchers_offset,
                       sizeof(offsets) - sizeof(offsets[0]));

where memcpy reads beyong &entry->watchers_offset to copy
{watchers,target,next}_offset altogether into offsets[]. Silence the
warning by wrapping these three up via struct_group().

[PATCH net-next 02/10] netfilter: ebtables: replace zero-length array members

[Florian Westphal]

From: "GONG, Ruiqi" <gongruiqi1@huawei.com>

As suggested by Kees[1], replace the old-style 0-element array members
of multiple structs in ebtables.h with modern C99 flexible array.

[1]: https://lore.kernel.org/all/5E8E0F9C-EE3F-4B0D-B827-DC47397E2A4A@kernel.org/

[ fw@strlen.de:
  keep struct ebt_entry_target as-is, causes compiler warning:
  "variable sized type 'struct ebt_entry_target' not at the end of a
  struct or class is a GNU extension" ]

Use `strscpy_pad` over `strncpy` for NUL-terminated strings.

We can also drop the + 1 from `NFT_OSF_MAXGENRELEN + 1` since `strscpy`
will guarantee NUL-termination.

[PATCH net-next 09/10] netfilter: xtables: refactor deprecated strncpy

[Florian Westphal]

From: Justin Stitt <justinstitt@google.com>

Prefer `strscpy_pad` as it's a more robust interface whilst maintaing
zero-padding behavior.

There may have existed a bug here due to both `tbl->repl.name` and
`info->name` having a size of 32 as defined below:
|  #define XT_TABLE_MAXNAMELEN 32

This may lead to buffer overreads in some situations -- `strscpy` solves
this by guaranteeing NUL-termination of the dest buffer.
