Thanks, Sasha ------------------ original commit in Linus's tree ------------------ From cefcd4fe2e3aaf792c14c9e56dab89e3d7a65d02 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel <ardb(a)kernel.org> Date: Fri, 22 Mar 2024 17:03:58 +0200 Subject: [PATCH] x86/efistub: Call mixed mode boot services on the firmware's stack Normally, the EFI stub calls into the EFI boot services using the stack that was live when the stub was entered. According to the UEFI spec, this stack needs to be at least 128k in size - this might seem large but all asynchronous processing and event handling in EFI runs from the same stack and so quite a lot of space may be used in practice. In mixed mode, the situation is a bit different: the bootloader calls the 32-bit EFI stub entry point, which calls the decompressor's 32-bit entry point, where the boot stack is set up, using a fixed allocation of 16k. This stack is still in use when the EFI stub is started in 64-bit mode, and so all calls back into the EFI firmware will be using the decompressor's limited boot stack. Due to the placement of the boot stack right after the boot heap, any stack overruns have gone unnoticed. However, commit 5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code") moved the definition of the boot heap into C code, and now the boot stack is placed right at the base of BSS, where any overruns will corrupt the end of the .data section. While it would be possible to work around this by increasing the size of the boot stack, doing so would affect all x86 systems, and mixed mode systems are a tiny (and shrinking) fraction of the x86 installed base. So instead, record the firmware stack pointer value when entering from the 32-bit firmware, and switch to this stack every time a EFI boot service call is made.

Lenovo 82TQ is unhappy if we do the display on sequence this late. The display output shows severe corruption. It's unclear if this is a failure on our part (perhaps something to do with sending commands in LP mode after HS /video mode transmission has been started? Though the backlight on command at least seems to work) or simply that there are some commands in the sequence that are needed to be done earlier (eg. could be some DSC init stuff?). If the latter then I don't think the current Windows code would work either, but maybe this was originally tested with an older driver, who knows. Root causing this fully would likely require a lot of experimentation which isn't really feasible without direct access to the machine, so let's just accept failure and go back to the original sequence.

This introduces a potential race condition in case of concurrent write and readdir operations. If the readdir operation initiates before a write has been processed by the server, it may update the file size attribute to an older value. Address this issue by avoiding file size updates from readdir when we have read/write lease. Scenario: 1) process1: open dir xyz 2) process1: readdir instance 1 on xyz 3) process2: create file.txt for write 4) process2: write x bytes to file.txt 5) process2: close file.txt 6) process2: open file.txt for read 7) process1: readdir 2 - overwrites file.txt inode size to 0 8) process2: read contents of file.txt - bug, short read with 0 bytes Cc: stable(a)vger.kernel.org Reviewed-by: Shyam Prasad N <sprasad(a)microsoft.com> Signed-off-by: Bharath SM <bharathsm(a)microsoft.com> Signed-off-by: Steve French <stfrench(a)microsoft.com> --- fs/smb/client/cifsproto.h | 6 ++++-- fs/smb/client/file.c | 8 +++++--- fs/smb/client/inode.c | 13 +++++++------ fs/smb/client/readdir.c | 2 +- 4 files changed, 17 insertions(+), 12 deletions(-) diff --git a/fs/smb/client/cifsproto.h b/fs/smb/client/cifsproto.h index a841bf4967fa4..58cfbd450a55e 100644 --- a/fs/smb/client/cifsproto.h +++ b/fs/smb/client/cifsproto.h @@ -144,7 +144,8 @@ extern int cifs_reconnect(struct TCP_Server_Info *server, extern int checkSMB(char *buf, unsigned int len, struct TCP_Server_Info *srvr);

DML pipes could be repopulated multiple times during single validate bandwidth attempt. We need to make sure that whenever we repopulate the dml pipes it is always aligned with the updated context. There is a case where DML pipes get repopulated during FPO optimization after ODM combine policy is changed. Since in the current code we reinitlaize ODM combine policy, even though the current context has ODM combine enabled, we overwrite it despite the pipes are already split. This causes DML to think that MPC combine is used so we mistakenly enable MPC combine because we apply pipe split with ODM combine policy reset. This issue doesn't impact non windowed MPO with ODM case because the legacy policy has restricted use cases. We don't encounter the case where both ODM and FPO optimizations are enabled together. So we decide to leave it as is because it is about to be replaced anyway.
