2023-10-10net: macsec: indicate next pn update when offloadingRadu Pirea (NXP OSS)
Indicate next PN update using update_pn flag in macsec_context. Offloaded MACsec implementations does not know whether or not the MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume that next PN should always updated, but this is not always true. The PN can be reset to its initial value using the following command: $ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case Or, the update PN command will succeed even if the driver does not support PN updates. $ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case Comparing the initial PN with the new PN value is not a solution. When the user updates the PN using its initial value the command will succeed, even if the driver does not support it. Like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@oss.nxp.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-10-10scsi: Do not rescan devices with a suspended queueDamien Le Moal
Commit ff48b37802e5 ("scsi: Do not attempt to rescan suspended devices") modified scsi_rescan_device() to avoid attempting rescanning a suspended device. However, the modification added a check to verify that a SCSI device is in the running state without checking if the device request queue (in the case of block device) is also running, thus allowing the exectuion of internal requests. Without checking the device request queue, commit ff48b37802e5 fix is incomplete and deadlocks on resume can still happen. Use blk_queue_pm_only() to check if the device request queue allows executing commands in addition to checking the SCSI device state.

2023-10-10ata: pata_parport: fit3: implement IDE command set registersOndrej Zary
fit3 protocol driver does not support accessing IDE control registers (device control/altstatus). The DOS driver does not use these registers either (as observed from DOSEMU trace). But the HW seems to be capable of accessing these registers - I simply tried bit 3 and it works! The control register is required to properly reset ATAPI devices or they will be detected only once (after a power cycle). Tested with EXP Computer CD-865 with MC-1285B EPP cable and TransDisk 3000.

2023-10-10ata: pata_parport: add custom version of wait_after_resetOndrej Zary
Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return bogus values when there's no master device present. This can cause reset to fail, preventing the lone slave device (such as EXP Computer CD-865) from working. Add custom version of wait_after_reset that ignores master failure when a slave device is present. The custom version is also needed because the generic ata_sff_wait_after_reset uses direct port I/O for slave device detection.

2023-10-10hv/hv_kvp_daemon:Support for keyfile based connection profileShradha Gupta
Ifcfg config file support in NetworkManger is deprecated. This patch provides support for the new keyfile config format for connection profiles in NetworkManager. The patch modifies the hv_kvp_daemon code to generate the new network configuration in keyfile format(.ini-style format) along with a ifcfg format configuration. The ifcfg format configuration is also retained to support easy backward compatibility for distro vendors. These configurations are stored in temp files which are further translated using the hv_set_ifconfig.sh script. This script is implemented by individual distros based on the network management commands supported. For example, RHEL's implementation could be found here: https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh Debian's implementation could be found here: https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig The next part of this support is to let the Distro vendors consume these modified implementations to the new configuration format.

2023-10-09bpf: Fix verifier log for async callback return valuesDavid Vernet
The verifier, as part of check_return_code(), verifies that async callbacks such as from e.g. timers, will return 0. It does this by correctly checking that R0->var_off is in tnum_const(0), which effectively checks that it's in a range of 0. If this condition fails, however, it prints an error message which says that the value should have been in (0x0; 0x1). This results in possibly confusing output such as the following in which an async callback returns 1: At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x1) The fix is easy -- we should just pass the tnum_const(0) as the correct range to verbose_invalid_scalar(), which will then print the following: At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x0) Fixes: bfc6bb74e4f1 ("bpf: Implement verifier support for validation of async callbacks.")
