Subject: [GIT PULL] Please pull RDMA subsystem changes

Hi Linus,

Collected fixes over the break. We made a bunch of progress on some of
the difficult syzkaller bugs. Otherwise lots of little driver bug fixes.

Thanks,
Jason

  RDMA/bnxt_re: fix dma_free_coherent() pointer (2025-12-30 06:45:51 -0500)

----------------------------------------------------------------
RDMA v6.19 first rc request

- Fix several syzkaller found bugs:
 * Poor parsing of the RDMA_NL_LS_OP_IP_RESOLVE netlink
 * GID entry refcount leaking when CM destruction races with multicast
   establishment
 * Missing refcount put in ib_del_sub_device_and_put()

- Fixup recently introduced uABI padding for 32 bit consistency

- Avoid user triggered math overflow in MANA and AFA

- Reading invalid netdev data during an event

- kdoc fixes

- Fix never-working gid copying in ib_get_gids_from_rdma_hdr

- Typo in bnxt when validating the BAR

- bnxt mis-parsed IB_SEND_IP_CSUM so it didn't work always

- bnxt out of bounds access in bnxt related to the counters on new devices

- Allocate the bnxt PDE table with the right sizing

- Use dma_free_coherent() correctly in bnxt

- Allow rxe to be unloadable when CONFIG_PROVE_LOCKING by adjusting the
  tracking of the global sockets it uses

- Missing unlocking on error path in rxe

- Compute the right number of pages in a MR in rtrs

----------------------------------------------------------------
