This is in fact 'disabled' in the spec, but there it's in a place where that actually makes sense. In our internal data structures, it doesn't really make sense, and in fact the previous commit just fixed a bug in that area. Make this safer by inverting the polarity from 'disabled' to 'enabled'.

The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files. The other changes were cases of more straightforward overlapping modifications. Signed-off-by: David S. Miller <davem@davemloft.net>
Kalle Valo says: ==================== wireless-drivers fixes for v5.8 Second set of fixes for v5.8, and hopefully also the last. Three important regressions fixed. ath9k * fix a regression which broke support for all ath9k usb devices ath10k * fix a regression which broke support for all QCA4019 AHB devices iwlwifi * fix a regression which broke support for some Killer Wireless-AC 1550 cards ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
Kalle Valo says: ==================== wireless-drivers-next patches for v5.9 First set of patches for v5.9. This comes later than usual as I was offline for two weeks. The biggest change here is moving Microchip wilc1000 driver from staging. There was an immutable topic branch with one commit moving the whole driver and the topic branch was pulled both to staging-next and wireless-drivers-next. At the moment the only reported conflict is in MAINTAINERS file, so I'm hoping the move should go smoothly. Other notable changes are ath11k getting 6 GHz band support and rtw88 supporting RTL8821CE. And there's also the usual fixes, API changes and cleanups all over. Major changes: wilc1000 * move from drivers/staging to drivers/net/wireless/microchip ath11k * add 6G band support * add spectral scan support iwlwifi * make FW reconfiguration quieter by not using warn level rtw88 * add support for RTL8821CE ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
This fixes a NULL pointer dereference in the probe path for AHB devices.
There attr parameter in the ath10k_ce_alloc_pipe() function is not
initialized, but accessed. This function is called by
ath10k_pci_setup_resource() which is called by ath10k_ahb_probe().
The struct ath10k_pci is also used for AHB devices and not only for PCI
devices.
The initialization of the new members of struct ath10k_pci is moved to
ath10k_pci_setup_resource() which is used by the PCI and the AHB code.
This also fixes a use after free bug in ath10k_pci_remove() when ar_pci
is accessed after ath10k_core_destroy() was called, which calls
ieee80211_free_hw() and frees this memory.
This fixes the following bug seen with backports-5.8-rc2 on OpenWrt on a
IPQ4019 device:

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.
