[ Upstream commit 51dd64bb99e4478fc5280171acd8e1b529eadaf7 ]
This reverts commit ccf11dbaa07b328fa469415c362d33459c140a37.
Commit ccf11dbaa07b ("evm: Fix memleak in init_desc") said there is memleak in init_desc. That may be incorrect, as we can see, tmp_tfm is saved in one of the two global variables hmac_tfm or evm_tfm[hash_algo], then if init_desc is called next time, there is no need to alloc tfm again, so in the error path of kmalloc desc or crypto_shash_init(desc), It is not a problem without freeing tmp_tfm.
And also that commit did not reset the global variable to NULL after freeing tmp_tfm and this makes *tfm a dangling pointer which may cause a UAF issue.

Due to TIF_SSBD and TIF_SPEC_IB the actual IA32_SPEC_CTRL value can differ from x86_spec_ctrl_base. As such, keep a per-CPU value reflecting the current task's MSR content.

When changing SPEC_CTRL for user control, the WRMSR can be delayed until return-to-user when KERNEL_IBRS has been enabled.
This avoids an MSR write during context switch.

I think there is a second problem with this patch:
If I create multiple station vdevs (on mtk7916 radio, not sure that matters much or not), and admin up a few of them, but leave remainder down, then the queues on the originally-down-vdevs are never started and so tx-path-hang on those stations.
I am not sure the best way to fix this.

The permission flags of newly created symlinks are wrongly dropped on nilfs2 with the current umask value even though symlinks should have 777 (rwxrwxrwx) permissions:
$ umask 0022 $ touch file && ln -s file symlink; ls -l file symlink -rw-r--r--. 1 root root 0 Jun 23 16:29 file lrwxr-xr-x. 1 root root 4 Jun 23 16:29 symlink -> file
This fixes the bug by inserting a missing check that excludes symlinks.

[ Upstream commit ccd3f449052449a917a3e577d8ba0368f43b8f29 ]
In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL.
This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.

[ Upstream commit e78276cadb669d3e55cffe66bd166ff3c8572e38 ]
Currently, the data flow of the max/min linkrate in the driver is
* in pm8001_get_lrate_mode(): hardcoded value ==> struct sas_phy
* in pm8001_bytes_dmaed(): struct pm8001_phy ==> struct sas_phy
* in pm8001_phy_control(): libsas data ==> struct pm8001_phy
Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), and the fields in struct pm8001_phy are not initialized, sysfs `/sys/class/sas_phy/phy-*/maximum_linkrate` always shows `Unknown`.
To fix the issue, change the dataflow to the following:
* in pm8001_phy_init(): initial value ==> struct pm8001_phy
* in pm8001_get_lrate_mode(): struct pm8001_phy ==> struct sas_phy
* in pm8001_phy_control(): libsas data ==> struct pm8001_phy
For negotiated linkrate, the current dataflow is:
* in pm8001_get_lrate_mode(): iomb data ==> struct asd_sas_phy ==> struct sas_phy
* in pm8001_bytes_dmaed(): struct asd_sas_phy ==> struct sas_phy
Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), the assignment statements in pm8001_bytes_dmaed() are unnecessary and cleaned up.
