      ====================
      Misc BPF updates
      
      This set cleans up ldimm64 leftovers from early eBPF days and
      adds couple of test cases related to this to the verifier test
      suite. It also cleans up the kallsyms spinlock (had same patch
      also in queue) by relaxing it through switching to _bh variant.
      It fixes up test_progs in relation to htons/ntohs and adds
      accessor macros for the percpu tests in test_maps.

      bpf: provide a generic macro for percpu values for selftests · f3515b5d
      Daniel Borkmann authored
      To overcome bugs as described and fixed in 89087c45 ("bpf: Fix
      values type used in test_maps"), provide a generic BPF_DECLARE_PERCPU()
      and bpf_percpu() accessor macro for all percpu map values used in
      tests.
      
      Declaring variables works as follows (also works for structs):
      
        BPF_DECLARE_PERCPU(uint32_t, my_value);
      
      They can then be accessed normally as uint32_t type through:
      
        bpf_percpu(my_value, <cpu_nr>)
      
      For example:
      
        bpf_percpu(my_value, 0)++;
      
      Implicitly, we make sure that the passed type is allocated and aligned
      by gcc at least on a 8-byte boundary, so that it works together with
      the map lookup/update syscall for percpu maps. We use it as a usage
      example in test_maps, so that others are free to adapt this into their
      code when necessary.

      bpf: fix _htons occurences in test_progs · 43bcf707
      Daniel Borkmann authored
      Dave reported that on sparc test_progs generates buggy swapped
      eth->h_proto protocol comparisons:

         R4=pkt(id=0,off=14,r=14) R5=inv56 R10=fp
      
      This is due to the unconditional ...
      
        #define htons __builtin_bswap16
        #define ntohs __builtin_bswap16
      
      ... in test_progs that causes this. Make use of asm/byteorder.h
      and use __constant_htons() where possible and only perform the
      bswap16 when on little endian in non-constant case.

      rhashtable: Do not lower max_elems when max_size is zero · 2d2ab658
      Herbert Xu authored
      The commit 6d684e54 ("rhashtable: Cap total number of entries
      to 2^31") breaks rhashtable users that do not set max_size.  This
      is because when max_size is zero max_elems is also incorrectly set
      to zero instead of 2^31.
      
      This patch fixes it by only lowering max_elems when max_size is not
      zero.

      mac80211: Fix possible sband related NULL pointer de-reference · 21a8e9dd
      Mohammed Shafi Shajakhan authored
      Existing API 'ieee80211_get_sdata_band' returns default 2 GHz band even
      if the channel context configuration is NULL. This crashes for chipsets
      which support 5 Ghz alone when it tries to access members of 'sband'.
      Channel context configuration can be NULL in multivif case and when
      channel switch is in progress (or) when it fails. Fix this by replacing
      the API 'ieee80211_get_sdata_band' with  'ieee80211_get_sband' which
      returns a NULL pointer for sband when the channel configuration is NULL.
      
      An example scenario is as below:
      
      In multivif mode (AP + STA) with drivers like ath10k, when we do a
      channel switch in the AP vif (which has a number of clients connected)
      and a STA vif which is connected to some other AP, when the channel
      switch in AP vif fails, while the STA vifs tries to connect to the
      other AP, there is a window where the channel context is NULL/invalid
      and this results in a crash  while the clients connected to the AP vif
      tries to reconnect and this race is very similar to the one investigated
      by Michal in https://patchwork.kernel.org/patch/3788161/ and this does
      happens with hardware that supports 5Ghz alone after long hours of
      testing with continuous channel switch on the AP vif

      mac80211: add ieee80211_tx_status_ext · 5fe49a9d
      Felix Fietkau authored
      This allows the driver to pass in struct ieee80211_tx_status directly.
      Make ieee80211_tx_status_noskb a wrapper around it.
      
      As with ieee80211_tx_status_noskb, there is no _ni variant of this call,
      because it probably won't be needed.
      
      Even if the driver won't provide any extra status info other than what's
      in struct ieee80211_tx_info already, it can optimize status reporting
      this way by passing in the station pointer.
