2024-09-10btrfs: update stripe_extent delete loop assumptionsJohannes Thumshirn1-0/+5
btrfs_delete_raid_extent() was written under the assumption, that it's call-chain always passes a start, length tuple that matches a single extent. But btrfs_delete_raid_extent() is called by do_free_extent_accounting() which in turn is called by __btrfs_free_extent(). But this call-chain passes in a start address and a length that can possibly match multiple on-disk extents. To make this possible, we have to adjust the start and length of each btree node lookup, to not delete beyond the requested range.

2024-09-05tools/net/ynl: fix cli.py --subscribe featureArkadiusz Kubalewski1-3/+4
Execution of command: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml / --subscribe "monitor" --sleep 10 fails with: File "/repo/./tools/net/ynl/cli.py", line 109, in main ynl.check_ntf() File "/repo/tools/net/ynl/lib/ynl.py", line 924, in check_ntf op = self.rsp_by_value[nl_msg.cmd()] KeyError: 19 Parsing Generic Netlink notification messages performs lookup for op in the message. The message was not yet decoded, and is not yet considered GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13). Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the op was not passed to the decode function, thus allow parsing of Generic Netlink notifications without causing the failure.

2024-09-05selftests: net: enable bind testsJamie Bainbridge1-1/+2
bind_wildcard is compiled but not run, bind_timewait is not compiled. These two tests complete in a very short time, use the test harness properly, and seem reasonable to enable. The author of the tests confirmed via email that these were intended to be run. Enable these two tests. Fixes: 13715acf8ab5 ("selftest: Add test for bind() conflicts.") Fixes: 2c042e8e54ef ("tcp: Add selftest for bind() and TIME_WAIT.")
