As I'm resigning from Intel, it's time to remove myself as a maintainer of iwlwifi. Good luck to Miri! Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Link: https://msgid.link/20240102122019.1689602-1-gregory.greenman@intel.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
The storage for the TLV PC register data wasn't done like all the other storage in the drv->fw area, which is cleared at the end of deallocation. Therefore, the freeing must also be done differently, explicitly NULL'ing it out after the free, since otherwise there's a nasty double-free bug here if a file fails to load after this has been parsed, and we get another free later (e.g. because no other file exists.) Fix that by adding the missing NULL assignment.

When a wiphy work is queued with timer, and then again without a delay, it's started immediately but *also* started again after the timer expires. This can lead, for example, to warnings in mac80211's offchannel code as reported by Jouni. Running the same work twice isn't expected, of course. Fix this by deleting the timer at this point, when queuing immediately due to delay=0.

We recently added some validation that we don't try to connect to an AP that is currently in a channel switch process, since that might want the channel to be quiet or we might not be able to connect in time to hear the switching in a beacon. This was in commit c09c4f3 ("wifi: mac80211: don't connect to an AP while it's in a CSA process"). However, we promptly got a report that this caused new connection failures, and it turns out that the AP that we now cannot connect to is permanently advertising an extended channel switch announcement, even with quiet. The AP in question was an Asus RT-AC53, with firmware 3.0.0.4.380_10760-g21a5898. As a first step, attempt to detect that we're dealing with such a situation, so mac80211 can use this later.

As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is happening we never connect to such an AP. Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response. Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that.

If a driver implements the change_interface() method, we switch interface type without taking the interface down, but still will recreate the debugfs for it since it's a new type.

As explained by a comment in <linux/u64_stats_sync.h>, write side of struct u64_stats_sync must ensure mutual exclusion, or one seqcount update could be lost on 32-bit platforms, thus blocking readers forever. Such lockups have been observed in real world after stmmac_xmit() on one CPU raced with stmmac_napi_poll_tx() on another CPU. To fix the issue without introducing a new lock, split the statics into three parts: 1. fields updated only under the tx queue lock, 2. fields updated only during NAPI poll, 3. fields updated only from interrupt context, Updates to fields in the first two groups are already serialized through other locks. It is sufficient to split the existing struct u64_stats_sync so that each group has its own. Note that tx_set_ic_bit is updated from both contexts. Split this counter so that each context gets its own, and calculate their sum to get the total value in stmmac_get_ethtool_stats(). For the third group, multiple interrupts may be processed by different CPUs at the same time, but interrupts on the same CPU will not nest. Move fields from this group to a newly created per-cpu struct stmmac_pcpu_stats.

cmsg_ipv6 test requests tcpdump to capture 4 packets, and sends until tcpdump quits. Only the first packet is "real", however, and the rest are basic UDP packets. So if tcpdump doesn't start in time it will miss the real packet and only capture the UDP ones. This makes the test fail on slow machine (no KVM or with debug enabled) 100% of the time, while it passes in fast environments. Repeat the "real" / expected packet.

The kernel build regressions/improvements email contained a couple of
issues with old compilers (in fact all the reports were on different
architectures, but all gcc 5.5) and the FIELD_PREP() and FIELD_GET()
conversions. They're all because an integer #define that should have
been declared as unsigned, was shifted to the point that it could set
the sign bit.
The fix just involves making sure the defines use the "U" identifier on
the constants to make sure they're unsigned. Should make the checkers
happier.
Confirmed with objdump before/after that there is no change to the
binaries.
Issues were reported as follows:

because the half of the destroy operations now executed by a

Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

Pipapo needs a scratchpad area to keep state during matching. This state can be large and thus cannot reside on stack. Each set preallocates percpu areas for this. On each match stage, one scratchpad half starts with all-zero and the other is inited to all-ones. At the end of each stage, the half that starts with all-ones is always zero. Before next field is tested, pointers to the two halves are swapped, i.e. resmap pointer turns into fill pointer and vice versa. After the last field has been processed, pipapo stashes the index toggle in a percpu variable, with assumption that next packet will start with the all-zero half and sets all bits in the other to 1. This isn't reliable. There can be multiple sets and we can't be sure that the upper and lower half of all set scratch map is always in sync (lookups can be conditional), so one set might have swapped, but other might not have been queried. Thus we need to keep the index per-set-and-cpu, just like the scratchpad. Note that this bug fix is incomplete, there is a related issue. avx2 and normal implementation might use slightly different areas of the map array space due to the avx2 alignment requirements, so m->scratch (generic/fallback implementation) and ->scratch_aligned (avx) may partially overlap. scratch and scratch_aligned are not distinct objects, the latter is just the aligned address of the former. After this change, write to scratch_align->map_index may write to scratch->map, so this issue becomes more prominent, we can set to 1 a bit in the supposedly-all-zero area of scratch->map[]. A followup patch will remove the scratch_aligned and makes generic and avx code use the same (aligned) area. Its done in a separate change to ease review.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Narrow down target/match revision to u8 in nft_compat.
2) Bail out with unused flags in nft_compat.
3) Restrict layer 4 protocol to u16 in nft_compat.
4) Remove static in pipapo get command that slipped through when
reducing set memory footprint.
5) Follow up incremental fix for the ipset performance regression,
this includes the missing gc cancellation, from Jozsef Kadlecsik.
6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0
as no filtering, from Felix Huettner.
7) Reject direction for NFT_CT_ID.
8) Use timestamp to check for set element expiration while transaction
is handled to prevent garbage collection from removing set elements
that were just added by this transaction. Packet path and netlink
dump/get path still use current time to check for expiration.
9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal.
10) map_index needs to be percpu and per-set, not just percpu.
At this time its possible for a pipapo set to fill the all-zero part
with ones and take the 'might have bits set' as 'start-from-zero' area.
From Florian Westphal. This includes three patches:
- Change scratchpad area to a structure that provides space for a
per-set-and-cpu toggle and uses it of the percpu one.
- Add a new free helper to prepare for the next patch.
- Remove the scratch_aligned pointer and makes AVX2 implementation
use the exact same memory addresses for read/store of the matching
state.
