[PATCH] powerpc/64s/radix/kfence: map __kfence_pool at page granularity

by Aboorva Devarajan

From: Hari Bathini <hbathini(a)linux.ibm.com> When KFENCE is enabled, total system memory is mapped at page level granularity. But in radix MMU mode, ~3GB additional memory is needed to map 100GB of system memory at page level granularity when compared to using 2MB direct mapping.This is not desired considering KFENCE is designed to be enabled in production kernels [1]. Mapping only the memory allocated for KFENCE pool at page granularity is sufficient to enable KFENCE support. So, allocate __kfence_pool during bootup and map it at page granularity instead of mapping all system memory at page granularity. Without patch: # cat /proc/meminfo MemTotal: 101201920 kB With patch: # cat /proc/meminfo MemTotal: 104483904 kB Note that enabling KFENCE at runtime is disabled for radix MMU for now, as it depends on the ability to split page table mappings and such APIs are not currently implemented for radix MMU. All kfence_test.c testcases passed with this patch.

[PATCH v4] platform/x86: intel_pmc_ipc: fix ACPI buffer memory leak

by yongxin.liu＠windriver.com

From: Yongxin Liu <yongxin.liu(a)windriver.com> The intel_pmc_ipc() function uses ACPI_ALLOCATE_BUFFER to allocate memory for the ACPI evaluation result but never frees it, causing a 192-byte memory leak on each call. This leak is triggered during network interface initialization when the stmmac driver calls intel_mac_finish() -> intel_pmc_ipc(). unreferenced object 0xffff96a848d6ea80 (size 192): comm "dhcpcd", pid 541, jiffies 4294684345 hex dump (first 32 bytes): 04 00 00 00 05 00 00 00 98 ea d6 48 a8 96 ff ff ...........H.... 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 ................ backtrace (crc b1564374): kmemleak_alloc+0x2d/0x40 __kmalloc_noprof+0x2fa/0x730 acpi_ut_initialize_buffer+0x83/0xc0 acpi_evaluate_object+0x29a/0x2f0 intel_pmc_ipc+0xfd/0x170 intel_mac_finish+0x168/0x230 stmmac_mac_finish+0x3d/0x50 phylink_major_config+0x22b/0x5b0 phylink_mac_initial_config.constprop.0+0xf1/0x1b0 phylink_start+0x8e/0x210 __stmmac_open+0x12c/0x2b0 stmmac_open+0x23c/0x380 __dev_open+0x11d/0x2c0 __dev_change_flags+0x1d2/0x250 netif_change_flags+0x2b/0x70 dev_change_flags+0x40/0xb0 Add __free(kfree) for ACPI object to properly release the allocated buffer.

[PATCH v2] ocfs2: fix kernel BUG in ocfs2_find_victim_chain

by Prithvi Tambewagh

syzbot reported a kernel BUG in ocfs2_find_victim_chain() because the `cl_next_free_rec` field of the allocation chain list is 0, triggring the BUG_ON(!cl->cl_next_free_rec) condition and panicking the kernel. To fix this, `cl_next_free_rec` is checked inside the caller of ocfs2_find_victim_chain() i.e. ocfs2_claim_suballoc_bits() and if it is equal to 0, ocfs2_error() is called, to log the corruption and force the filesystem into read-only mode, to prevent further damage.

[PATCH 6.1.y v1 0/2] mptcp: Fix conflicts between MPTCP and sockmap

by Jiayuan Chen

Overall, we encountered a warning [1] that can be triggered by running the selftest I provided. sockmap works by replacing sk_data_ready, recvmsg, sendmsg operations and implementing fast socket-level forwarding logic: 1. Users can obtain file descriptors through userspace socket()/accept() interfaces, then call BPF syscall to perform these replacements. 2. Users can also use the bpf_sock_hash_update helper (in sockops programs) to replace handlers when TCP connections enter ESTABLISHED state (BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB/BPF_SOCK_OPS_ACTIVE_ESTABLISHED_CB) However, when combined with MPTCP, an issue arises: MPTCP creates subflow sk's and performs TCP handshakes, so the BPF program obtains subflow sk's and may incorrectly replace their sk_prot. We need to reject such operations. In patch 1, we set psock_update_sk_prot to NULL in the subflow's custom sk_prot. Additionally, if the server's listening socket has MPTCP enabled and the client's TCP also uses MPTCP, we should allow the combination of subflow and sockmap. This is because the latest Golang programs have enabled MPTCP for listening sockets by default [2]. For programs already using sockmap, upgrading Golang should not cause sockmap functionality to fail. Patch 2 prevents the panic from occurring. Despite these patches fixing stream corruption, users of sockmap must set GODEBUG=multipathtcp=0 to disable MPTCP until sockmap fully supports it.

[PATCH AUTOSEL 6.17-6.12] Revert "drm/amd/display: Move setup_stream_attribute"

by Sasha Levin

From: Alex Deucher <alexander.deucher(a)amd.com> [ Upstream commit 3126c9ccb4373d8758733c6699ba5ab93dbe5c9d ] This reverts commit 2681bf4ae8d24df950138b8c9ea9c271cd62e414. This results in a blank screen on the HDMI port on some systems. Revert for now so as not to regress 6.18, can be addressed in 6.19 once the issue is root caused. Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4652 Cc: Sunpeng.Li(a)amd.com Cc: ivan.lipski(a)amd.com Signed-off-by: Alex Deucher <alexander.deucher(a)amd.com> (cherry picked from commit d0e9de7a81503cdde37fb2d37f1d102f9e0f38fb) Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: Now I have a complete understanding of the issue. Let me summarize my analysis: ## Comprehensive Analysis ### 1. Commit Message Analysis This is a **revert** of commit `2681bf4ae8d24df950138b8c9ea9c271cd62e414` that moved `setup_stream_attribute()` from `link_set_dpms_on()` to individual `enable_stream()` functions. The commit clearly states: - The change "results in a blank screen on the HDMI port on some systems" - Includes a bug report link: https://gitlab.freedesktop.org/drm/amd/-/issues/4652 - Explicitly intended to "not regress 6.18" - Cherry-picked from upstream with maintainer sign-off ### 2. Critical Finding: Buggy Commit Already Backported **The original problematic commit (`7965cb360655`) was already backported to stable trees** (as shown by `[ Upstream commit ... ]` and Sasha Levin's signature). This means **stable users are currently affected by this regression** and need the fix. ### 3. Technical Root Cause The original commit attempted to fix a symclk RCO clock gating issue by moving `setup_stream_attribute()` later in the sequence, after clock ungating in `enable_stream()`. However: - **For DP (DisplayPort)**: This ordering works because DP needs symclk ungated first - **For HDMI/TMDS**: The stream attributes must be set earlier, specifically before VPG power-on and infoframe construction in `link_set_dpms_on()` The code at line 3055 in `dcn20_hwseq.c` shows where the call was moved: ```c link_hwss->setup_stream_attribute(pipe_ctx); ``` This call happens too late for HDMI paths, causing blank screens because the HDMI signal initialization sequence depends on attributes being programmed before the display pipe is fully enabled. ### 4. Code Change Assessment The revert is small and surgical: - **5 files changed** - Removes `link_hwss->setup_stream_attribute()` from 3 hwseq files (dce110, dcn20, dcn401) - Restores the call in `link_dpms.c` at the correct position (after `set_out_mux()`, before VPG power-on) - Removes unused LVDS stub from virtual_stream_encoder.c ### 5. Stable Kernel Rules Compliance | Criteria | Assessment | |----------|------------| | Fixes a real bug affecting users | ✅ Blank HDMI screen - severe user- visible regression | | Obviously correct | ✅ Simple revert to known-working code | | Small and contained | ✅ ~20 lines removed, ~5 lines added | | No new features | ✅ Pure regression fix | | Bug exists in stable | ✅ Original buggy commit was backported | ### 6. Risk Assessment - **Regression risk: LOW** - This reverts to previously known-working behavior that was stable for years - **Trade-off**: The original symclk RCO issue will remain unfixed, but: - RCO issue affects a narrow DP corner case - Blank HDMI affects common consumer hardware - A blank screen is a far worse failure than the clock gating issue - **Testing**: Upstream maintainer sign-off (Alex Deucher) and cherry- picked from mainline ### 7. User Impact - **Severity: CRITICAL** - Complete display failure on HDMI - **Scope: HIGH** - HDMI is ubiquitous; affects multiple hardware generations (dce110, dcn20, dcn401) - **Real users affected**: Bug report confirms actual user impact ### Conclusion This commit is an **ideal stable backport candidate**: 1. The regression-causing commit was already backported to stable trees, so stable users are currently broken 2. It fixes a critical user-visible bug (blank HDMI displays) 3. The fix is a simple, safe revert to known-good code 4. It has proper upstream maintainer approval 5. The risk of the revert causing problems is minimal (returning to proven behavior) The revert is **mandatory** for any stable tree that includes commit `7965cb360655` to restore working HDMI functionality. **YES** drivers/gpu/drm/amd/display/dc/hwss/dce110/dce110_hwseq.c | 1 - drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c | 2 -- drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c | 2 -- drivers/gpu/drm/amd/display/dc/link/link_dpms.c | 3 +++ .../drm/amd/display/dc/virtual/virtual_stream_encoder.c | 7 ------- 5 files changed, 3 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/hwss/dce110/dce110_hwseq.c b/drivers/gpu/drm/amd/display/dc/hwss/dce110/dce110_hwseq.c index 537f53811460..39de51cbbde9 100644 --- a/drivers/gpu/drm/amd/display/dc/hwss/dce110/dce110_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/hwss/dce110/dce110_hwseq.c @@ -671,7 +671,6 @@ void dce110_enable_stream(struct pipe_ctx *pipe_ctx) uint32_t early_control = 0; struct timing_generator *tg = pipe_ctx->stream_res.tg; - link_hwss->setup_stream_attribute(pipe_ctx); link_hwss->setup_stream_encoder(pipe_ctx); dc->hwss.update_info_frame(pipe_ctx); diff --git a/drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c b/drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c index f7b72b24b750..921023500bec 100644 --- a/drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/hwss/dcn20/dcn20_hwseq.c @@ -3052,8 +3052,6 @@ void dcn20_enable_stream(struct pipe_ctx *pipe_ctx) link_enc->transmitter - TRANSMITTER_UNIPHY_A); } - link_hwss->setup_stream_attribute(pipe_ctx); - if (dc->res_pool->dccg->funcs->set_pixel_rate_div) dc->res_pool->dccg->funcs->set_pixel_rate_div( dc->res_pool->dccg, diff --git a/drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c b/drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c index 0fe763704945..b95b98cc2553 100644 --- a/drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c @@ -968,8 +968,6 @@ void dcn401_enable_stream(struct pipe_ctx *pipe_ctx) } } - link_hwss->setup_stream_attribute(pipe_ctx); - if (dc->res_pool->dccg->funcs->set_pixel_rate_div) { dc->res_pool->dccg->funcs->set_pixel_rate_div( dc->res_pool->dccg, diff --git a/drivers/gpu/drm/amd/display/dc/link/link_dpms.c b/drivers/gpu/drm/amd/display/dc/link/link_dpms.c index cb80b4599936..8c8682f743d6 100644 --- a/drivers/gpu/drm/amd/display/dc/link/link_dpms.c +++ b/drivers/gpu/drm/amd/display/dc/link/link_dpms.c @@ -2458,6 +2458,7 @@ void link_set_dpms_on( struct link_encoder *link_enc = pipe_ctx->link_res.dio_link_enc; enum otg_out_mux_dest otg_out_dest = OUT_MUX_DIO; struct vpg *vpg = pipe_ctx->stream_res.stream_enc->vpg; + const struct link_hwss *link_hwss = get_link_hwss(link, &pipe_ctx->link_res); bool apply_edp_fast_boot_optimization = pipe_ctx->stream->apply_edp_fast_boot_optimization; @@ -2501,6 +2502,8 @@ void link_set_dpms_on( pipe_ctx->stream_res.tg->funcs->set_out_mux(pipe_ctx->stream_res.tg, otg_out_dest); } + link_hwss->setup_stream_attribute(pipe_ctx); + pipe_ctx->stream->apply_edp_fast_boot_optimization = false; // Enable VPG before building infoframe diff --git a/drivers/gpu/drm/amd/display/dc/virtual/virtual_stream_encoder.c b/drivers/gpu/drm/amd/display/dc/virtual/virtual_stream_encoder.c index 6ffc74fc9dcd..ad088d70e189 100644 --- a/drivers/gpu/drm/amd/display/dc/virtual/virtual_stream_encoder.c +++ b/drivers/gpu/drm/amd/display/dc/virtual/virtual_stream_encoder.c @@ -44,11 +44,6 @@ static void virtual_stream_encoder_dvi_set_stream_attribute( struct dc_crtc_timing *crtc_timing, bool is_dual_link) {} -static void virtual_stream_encoder_lvds_set_stream_attribute( - struct stream_encoder *enc, - struct dc_crtc_timing *crtc_timing) -{} - static void virtual_stream_encoder_set_throttled_vcp_size( struct stream_encoder *enc, struct fixed31_32 avg_time_slots_per_mtp) @@ -120,8 +115,6 @@ static const struct stream_encoder_funcs virtual_str_enc_funcs = { virtual_stream_encoder_hdmi_set_stream_attribute, .dvi_set_stream_attribute = virtual_stream_encoder_dvi_set_stream_attribute, - .lvds_set_stream_attribute = - virtual_stream_encoder_lvds_set_stream_attribute, .set_throttled_vcp_size = virtual_stream_encoder_set_throttled_vcp_size, .update_hdmi_info_packets = -- 2.51.0
