2024-04-22cxl/core: Fix potential payload size confusion in cxl_mem_get_poison()Dan Williams
A recent change to cxl_mem_get_records_log() [1] highlighted a subtle nuance of looping calls to cxl_internal_send_cmd(), i.e. that cxl_internal_send_cmd() modifies the 'size_out' member of the @mbox_cmd argument. That mechanism is useful for communicating underflow, but it is unwanted when reusing @mbox_cmd for a subsequent submission. It turns out that cxl_xfer_log() avoids this scenario by always redefining @mbox_cmd each iteration. Update cxl_mem_get_records_log() and cxl_mem_get_poison() to follow the same style as cxl_xfer_log(), i.e. re-define @mbox_cmd each iteration. The cxl_mem_get_records_log() change is just a style fixup, but the cxl_mem_get_poison() change is a potential fix, per Alison [2]: Poison list retrieval can hit this case if the MORE flag is set and a follow on read of the list delivers more records than the previous read. ie. device gives one record, sets the _MORE flag, then gives 5. Not an urgent fix since this behavior has not been seen in the wild, but worth tracking as a fix.

2024-04-22cifs: reinstate original behavior again for forceuid/forcegidTakayuki Nagata
forceuid/forcegid should be enabled by default when uid=/gid= options are specified, but commit 24e0a1eff9e2 ("cifs: switch to new mount api") changed the behavior. Due to the change, a mounted share does not show intentional uid/gid for files and directories even though uid=/gid= options are specified since forceuid/forcegid are not enabled.

Detect and mitigate inode collsions that now occur since we fixed 9p generating duplicate inode structures. Underlying cause of these appears to be a race condition between reuse of inode numbers in underlying file system and cleanup of inode numbers in the client. Enabling caching makes this much more likely to happen as it increases cleanup latency due to writebacks.

2024-04-22arm32, bpf: Reimplement sign-extension mov instructionPuranjay Mohan
The current implementation of the mov instruction with sign extension has the following problems: 1. It clobbers the source register if it is not stacked because it sign extends the source and then moves it to the destination. 2. If the dst_reg is stacked, the current code doesn't write the value back in case of 64-bit mov. 3. There is room for improvement by emitting fewer instructions. The steps for fixing this and the instructions emitted by the JIT are explained below with examples in all combinations: Case A: offset == 32: ===================== Case A.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Store tmp_lo into dst_lo 3. Sign extend tmp_lo into tmp_hi 4. Store tmp_hi to dst_hi Example: r3 = (s32)r3 r3 is a stacked register ldr r6, [r11, #-16] // Load r3_lo into tmp_lo // str to dst_lo is not emitted because src_lo == dst_lo asr r7, r6, #31 // Sign extend tmp_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi into r3_hi Case A.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo into dst_hi Example: r6 = (s32)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked ldr r4, [r11, #-16] // Load r3_lo into r6_lo asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case A.3: src is not stacked but dst is stacked: ------------------------------------------------ 1. Store src_lo into dst_lo 2. Sign extend src_lo into tmp_hi 3. Store tmp_hi to dst_hi Example: r3 = (s32)r6 r3 is stacked and r6 maps to {ARM_R5, ARM_R4} str r4, [r11, #-16] // Store r6_lo to r3_lo asr r7, r4, #31 // Sign extend r6_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi to dest_hi Case A.4: Both src and dst are not stacked: ------------------------------------------- 1. Mov src_lo into dst_lo 2. Sign extend src_lo into dst_hi Example: (bf) r6 = (s32)r6 r6 maps to {ARM_R5, ARM_R4} // Mov not emitted because dst == src asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case B: offset != 32: ===================== Case B.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Sign extend tmp_lo according to offset. 3. Store tmp_lo into dst_lo 4. Sign extend tmp_lo into tmp_hi 5. Store tmp_hi to dst_hi Example: r9 = (s8)r3 r9 and r3 are both stacked registers ldr r6, [r11, #-16] // Load r3_lo into tmp_lo lsl r6, r6, #24 // Sign extend tmp_lo asr r6, r6, #24 // .. str r6, [r11, #-56] // Store tmp_lo to r9_lo asr r7, r6, #31 // Sign extend tmp_lo to tmp_hi str r7, [r11, #-52] // Store tmp_hi to r9_hi Case B.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo according to offset. 3. Sign extend tmp_lo into dst_hi Example: r6 = (s8)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked ldr r4, [r11, #-16] // Load r3_lo to r6_lo lsl r4, r4, #24 // Sign extend r6_lo asr r4, r4, #24 // .. asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case B.3: src is not stacked but dst is stacked: ------------------------------------------------ 1.

2024-04-22sched/eevdf: Prevent vlag from going out of bounds in reweight_eevdf()Xuewen Yan
It was possible to have pick_eevdf() return NULL, which then causes a NULL-deref. This turned out to be due to entity_eligible() returning falsely negative because of a s64 multiplcation overflow. Specifically, reweight_eevdf() computes the vlag without considering the limit placed upon vlag as update_entity_lag() does, and then the scaling multiplication (remember that weight is 20bit fixed point) can overflow. This then leads to the new vruntime being weird which then causes the above entity_eligible() to go side-ways and claim nothing is eligible. Thus limit the range of vlag accordingly. All this was quite rare, but fatal when it does happen.

2024-04-22s390/mm: Fix clearing storage keys for huge pagesClaudio Imbrenda
The function __storage_key_init_range() expects the end address to be the first byte outside the range to be initialized. I.e. end - start should be the size of the area to be initialized. The current code works because __storage_key_init_range() will still loop over every page in the range, but it is slower than using sske_frame().

Commit dce0919c83c3 ("irqchip/renesas-rzg2l: Do not set TIEN and TINT source at the same time") removed the setup of TINT from rzg2l_irqc_irq_enable(). To address the spurious interrupt issue the setup of TINT has been moved in rzg2l_tint_set_edge() through rzg2l_disable_tint_and_set_tint_source(). With this, the interrupts are not properly re-configured after a suspend-to-RAM cycle. To address this issue and avoid spurious interrupts while resumming set the interrupt type before enabling it.

In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software. When a robust management frame is received, rx_dec->swdec is not set, even though the HW did not decrypt it. Extend the check and don't set RX_FLAG_DECRYPTED for these frames in order to use SW decryption. Use the security flag in the RX descriptor for this purpose, like it is done in the rtw88 driver.
