      bnxt_en: take coredump_record structure off stack · 1bbf3aed
      由 Arnd Bergmann 提交于 
      The bnxt_coredump_record structure is very long, causing a warning
about possible stack overflow on 32-bit architectures:

drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c: In function 'bnxt_get_coredump':
drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:2989:1: error: the frame size of 1188 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

I could not see any reason to operate on an on-stack copy of the
structure before copying it back into the caller-provided buffer, which
also simplifies the code here.

      net: systemport: fix unused function warning · cf87615d
      由 Arnd Bergmann 提交于 
      The only remaining caller of this function is inside of an #ifdef
after another caller got removed. This causes a harmless warning
in some configurations:

drivers/net/ethernet/broadcom/bcmsysport.c:1068:13: error: 'bcm_sysport_resume_from_wol' defined but not used [-Werror=unused-function]

Removing the #ifdef around the PM functions simplifies the code
and avoids the problem but letting the compiler drop the unused
functions silently.

      l2tp: fix unused function warning · c2ebc256
      由 Arnd Bergmann 提交于 
      Removing one of the callers of pppol2tp_session_get_sock caused a harmless
warning in some configurations:

net/l2tp/l2tp_ppp.c:142:21: 'pppol2tp_session_get_sock' defined but not used [-Wunused-function]

Rather than adding another #ifdef here, using a proper IS_ENABLED()
check makes the code more readable and avoids those warnings while
letting the compiler figure out for itself which code is needed.

This adds one pointer for the unused show() callback in struct
l2tp_session, but that seems harmless.

      bnxt_en: avoid string overflow for record->system_name · 3d46eee5
      由 Arnd Bergmann 提交于 
      The utsname()->nodename string may be 64 bytes long, and it gets
copied without the trailing nul byte into the shorter record->system_name,
as gcc now warns:

In file included from include/linux/bitmap.h:9,
                 from include/linux/ethtool.h:16,
                 from drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:13:

include/linux/string.h:254:9: error: '__builtin_strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]

Using strlcpy() at least avoids overflowing the destination buffer
and adds proper nul-termination. It may still truncate long names
though, which probably can't be solved here.

Those #ifdef checks are hard to get right, replace them all with
IS_ENABLED() checks that leave the same code visible to the compiler
but let it optimize out the unused bits based on the configuration.

This is because we didn't update f->result.res when create new filter. Then in
tcindex_delete() -> tcf_unbind_filter(), we will failed to find out the res
and unbind filter, which will trigger the WARN_ON() in cbq_destroy_class().

Fix it by updating f->result.res when create new filter.

tc qdisc add dev lo parent 2:1 pfifo limit 5
tc qdisc del dev lo root

This is because in tcindex_set_parms, when there is no old_r, we set new
exts to cr.exts. And we didn't set it to filter when r == &new_filter_result.

Then in tcindex_delete() -> tcf_exts_get_net(), we will get NULL pointer
dereference as we didn't init exts.

Fix it by moving tcf_exts_change() after "if (old_r && old_r != r)" check.
Then we don't need "cr" as there is no errout after that.

====================
mlx5e-updates-2018-08-10

This series provides the following updates to mlx5e netdevice driver.

1) First 4 patches extends the support for ethtool rxnfc flow steering
   - Added ipv6 support
   - l4 proto ip field for both ip6 and ip4

2) Next 4 patches, reorganizing flow steering structures and declaration into
one header file, and add two Kconfig flags to allow disabling/enabling mlx5
netdevice rx flow steering at compile time:
CONFIG_MLX5_EN_ARFS for en_arfs.c
CONFIG_MLX5_EN_RXNFC for en_fs_ehtool.c

3) More kconfig flags dependencies
- vxlan.c depends on CONFIG_VXLAN
- clock.c depends on CONFIG_PTP_1588_CLOCK

4) Reorganize the Makefile
