2024-01-02net: bcmgenet: Fix FCS generation for fragmented skbuffsAdrian Cinal
The flag DMA_TX_APPEND_CRC was only written to the first DMA descriptor in the TX path, where each descriptor corresponds to a single skbuff fragment (or the skbuff head). This led to packets with no FCS appearing on the wire if the kernel allocated the packet in fragments, which would always happen when using PACKET_MMAP/TPACKET (cf. tpacket_fill_skb() in net/af_packet.c).

2024-01-02net: ethtool: Fix symmetric-xor RSS RX flow hash checkGerhard Engleder
Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash") adds a check to the ethtool set_rxnfc operation, which checks the RX flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced with the same commit. It calls the ethtool get_rxfh operation to get the RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is returned. There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which support the ethtool operation set_rxnfc but not get_rxfh. This results in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all these drivers. Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX flow hash.

2024-01-02mptcp: prevent tcp diag from closing listener subflowsPaolo Abeni
The MPTCP protocol does not expect that any other entity could change the first subflow status when such socket is listening. Unfortunately the TCP diag interface allows aborting any TCP socket, including MPTCP listeners subflows. As reported by syzbot, that trigger a WARN() and could lead to later bigger trouble. The MPTCP protocol needs to do some MPTCP-level cleanup actions to properly shutdown the listener. To keep the fix simple, prevent entirely the diag interface from stopping such listeners. We could refine the diag callback in a later, larger patch targeting net-next.

2024-01-02tracefs: Check for dentry->d_inode exists in set_gid()Steven Rostedt (Google)
If a getdents() is called on the tracefs directory but does not get all the files, it can leave a "cursor" dentry in the d_subdirs list of tracefs dentry. This cursor dentry does not have a d_inode for it. Before referencing tracefs_inode from the dentry, the d_inode must first be checked if it has content. If not, then it's not a tracefs_inode and can be ignored. The following caused a crash: #define getdents64(fd, dirp, count) syscall(SYS_getdents64, fd, dirp, count) #define BUF_SIZE 256 #define TDIR "/tmp/file0" int main(void) { char buf[BUF_SIZE]; int fd; int n; mkdir(TDIR, 0777); mount(NULL, TDIR, "tracefs", 0, NULL); fd = openat(AT_FDCWD, TDIR, O_RDONLY); n = getdents64(fd, buf, BUF_SIZE); ret = mount(NULL, TDIR, NULL, MS_NOSUID|MS_REMOUNT|MS_RELATIME|MS_LAZYTIME, "gid=1000"); return 0; } That's because the 256 BUF_SIZE was not big enough to read all the dentries of the tracefs file system and it left a "cursor" dentry in the subdirs of the tracefs root inode. Then on remounting with "gid=1000", it would cause an iteration of all dentries which hit: ti = get_tracefs(dentry->d_inode); if (ti && (ti->flags & TRACEFS_EVENT_INODE)) eventfs_update_gid(dentry, gid); Which crashed because of the dereference of the cursor dentry which had a NULL d_inode. In the subdir loop of the dentry lookup of set_gid(), if a child has a NULL d_inode, simply skip it.

2024-01-02ice: replace ice_vf_recreate_vsi() with ice_vf_reconfig_vsi()Jacob Keller
The ice_vf_create_vsi() function and its VF ops helper introduced by commit a4c785e8162e ("ice: convert vf_ops .vsi_rebuild to .create_vsi") are used during an individual VF reset to re-create the VSI. This was done in order to ensure that the VSI gets properly reconfigured within the hardware. This is somewhat heavy handed as we completely release the VSI memory and structure, and then create a new VSI. This can also potentially force a change of the VSI index as we will re-use the first open slot in the VSI array which may not be the same. As part of implementing devlink reload, commit 6624e780a577 ("ice: split ice_vsi_setup into smaller functions") split VSI setup into smaller functions, introducing both ice_vsi_cfg() and ice_vsi_decfg() which can be used to configure or deconfigure an existing software VSI structure. Rather than completely removing the VSI and adding a new one using the .create_vsi() VF operation, simply use ice_vsi_decfg() to remove the current configuration. Save the VSI type and then call ice_vsi_cfg() to reconfigure the VSI as the same type that it was before. The existing reset logic assumes that all hardware filters will be removed, so also call ice_fltr_remove_all() before re-configuring the VSI. This new operation does not re-create the VSI, so rename it to ice_vf_reconfig_vsi(). The new approach can safely share the exact same flow for both SR-IOV VFs as well as the Scalable IOV VFs being worked on. This uses less code and is a better abstraction over fully deleting the VSI and adding a new one.

2024-01-02ice: Add support for packet mirroring using hardware in switchdev modeAndrii Staikov
Switchdev mode allows to add mirroring rules to mirror incoming and outgoing packets to the interface's port representor. Previously, this was available only using software functionality. Add possibility to offload this functionality to the NIC hardware. Introduce ICE_MIRROR_PACKET filter action to the ice_sw_fwd_act_type enum to identify the desired action and pass it to the hardware as well as the VSI to mirror.

2024-01-02ice: Enable SW interrupt from FW for LL TSKarol Kolacinski
Introduce new capability - Low Latency Timestamping with Interrupt. On supported devices, driver can request a single timestamp from FW without polling the register afterwards. Instead, FW can issue a dedicated interrupt when the timestamp was read from the PHY register and its value is available to read from the register. This eliminates the need of bottom half scheduling, which results in minimal delay for timestamping. For this mode, allocate TS indices sequentially, so that timestamps are always completed in FIFO manner.

2024-01-02virt: sev-guest: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-01-02mmc: mmc_spi: remove custom DMA mapped buffersAndy Shevchenko
There is no need to duplicate what SPI core or individual controller drivers already do, i.e. mapping the buffers for DMA capable transfers. Note, that the code, besides its redundancy, was buggy: strictly speaking there is no guarantee, while it's true for those which can use this code (see below), that the SPI host controller _is_ the device which does DMA. Also see the Link tags below. Additional notes. Currently only two SPI host controller drivers may use premapped (by the user) DMA buffers: - drivers/spi/spi-au1550.c - drivers/spi/spi-fsl-spi.c Both of them have DMA mapping support code. I don't expect that SPI host controller code is worse than what has been done in mmc_spi. Hence I do not expect any regressions here. Otherwise, I'm pretty much sure these regressions have to be fixed in the respective drivers, and not here. That said, remove all related pieces of DMA mapping code from mmc_spi.
