2024-10-09Revert "mm: introduce PF_MEMALLOC_NORECLAIM, PF_MEMALLOC_NOWARN"Michal Hocko2-15/+6
This reverts commit eab0af905bfc3e9c05da2ca163d76a1513159aa4. There is no existing user of those flags. PF_MEMALLOC_NOWARN is dangerous because a nested allocation context can use GFP_NOFAIL which could cause unexpected failure. Such a code would be hard to maintain because it could be deeper in the call chain. PF_MEMALLOC_NORECLAIM has been added even when it was pointed out [1] that such a allocation contex is inherently unsafe if the context doesn't fully control all allocations called from this context. While PF_MEMALLOC_NOWARN is not dangerous the way PF_MEMALLOC_NORECLAIM is it doesn't have any user and as Matthew has pointed out we are running out of those flags so better reclaim it without any real users.

2024-10-09bcachefs: do not use PF_MEMALLOC_NORECLAIMMichal Hocko2-3/+8
Patch series "remove PF_MEMALLOC_NORECLAIM" v3. This patch (of 2): bch2_new_inode relies on PF_MEMALLOC_NORECLAIM to try to allocate a new inode to achieve GFP_NOWAIT semantic while holding locks. If this allocation fails it will drop locks and use GFP_NOFS allocation context. We would like to drop PF_MEMALLOC_NORECLAIM because it is really dangerous to use if the caller doesn't control the full call chain with this flag set. E.g. if any of the function down the chain needed GFP_NOFAIL request the PF_MEMALLOC_NORECLAIM would override this and cause unexpected failure. While this is not the case in this particular case using the scoped gfp semantic is not really needed bacause we can easily pus the allocation context down the chain without too much clutter.

This scenario shows that all notification groups are in principle prone to this kind of a deadlock (previously, we considered only fanotify and dnotify to be problematic for other reasons) so make sure all allocations under group->mark_mutex happen with GFP_NOFS.

2024-10-01net: Fix gso_features_check to check for both dev->gso_{ipv4_,}max_sizeDaniel Borkmann1-0/+9
Commit 24ab059d2ebd ("net: check dev->gso_max_size in gso_features_check()") added a dev->gso_max_size test to gso_features_check() in order to fall back to GSO when needed. This was added as it was noticed that some drivers could misbehave if TSO packets get too big. However, the check doesn't respect dev->gso_ipv4_max_size limit. For instance, a device could be configured with BIG TCP for IPv4, but not IPv6. Therefore, add a netif_get_gso_max_size() equivalent to netif_get_gro_max_size() and use the helper to respect both limits before falling back to GSO engine.

2024-09-29close_range(): fix the logics in descriptor table trimmingAl Viro1-4/+4
Cloning a descriptor table picks the size that would cover all currently opened files. That's fine for clone() and unshare(), but for close_range() there's an additional twist - we clone before we close, and it would be a shame to have close_range(3, ~0U, CLOSE_RANGE_UNSHARE) leave us with a huge descriptor table when we are not going to keep anything past stderr, just because some large file descriptor used to be open before our call has taken it out. Unfortunately, it had been dealt with in an inherently racy way - sane_fdtable_size() gets a "don't copy anything past that" argument (passed via unshare_fd() and dup_fd()), close_range() decides how much should be trimmed and passes that to unshare_fd(). The problem is, a range that used to extend to the end of descriptor table back when close_range() had looked at it might very well have stuff grown after it by the time dup_fd() has allocated a new files_struct and started to figure out the capacity of fdtable to be attached to that. That leads to interesting pathological cases; at the very least it's a QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes a snapshot of descriptor table one might have observed at some point. Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination of unshare(CLONE_FILES) with plain close_range(), ending up with a weird state that would never occur with unshare(2) is confusing, to put it mildly. It's not hard to get rid of - all it takes is passing both ends of the range down to sane_fdtable_size(). There we are under ->files_lock, so the race is trivially avoided. So we do the following: * switch close_files() from calling unshare_fd() to calling dup_fd(). * undo the calling convention change done to unshare_fd() in 60997c3d45d9 "close_range: add CLOSE_RANGE_UNSHARE" * introduce struct fd_range, pass a pointer to that to dup_fd() and sane_fdtable_size() instead of "trim everything past that point" they are currently getting. NULL means "we are not going to be punching any holes"; NR_OPEN_MAX is gone. * make sane_fdtable_size() use find_last_bit() instead of open-coding it; it's easier to follow that way. * while we are at it, have dup_fd() report errors by returning ERR_PTR(), no need to use a separate int *errorp argument.

Pull x86 kvm updates from Paolo Bonzini: "x86: - KVM currently invalidates the entirety of the page tables, not just those for the memslot being touched, when a memslot is moved or deleted. This does not traditionally have particularly noticeable overhead, but Intel's TDX will require the guest to re-accept private pages if they are dropped from the secure EPT, which is a non starter. Actually, the only reason why this is not already being done is a bug which was never fully investigated and caused VM instability with assigned GeForce GPUs, so allow userspace to opt into the new behavior. - Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10 functionality that is on the horizon) - Rework common MSR handling code to suppress errors on userspace accesses to unsupported-but-advertised MSRs This will allow removing (almost?) all of KVM's exemptions for userspace access to MSRs that shouldn't exist based on the vCPU model (the actual cleanup is non-trivial future work) - Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the 64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv) stores the entire 64-bit value at the ICR offset - Fix a bug where KVM would fail to exit to userspace if one was triggered by a fastpath exit handler - Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when there's already a pending wake event at the time of the exit - Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the nested guest) - Overhaul the "unprotect and retry" logic to more precisely identify cases where retrying is actually helpful, and to harden all retry paths against putting the guest into an infinite retry loop - Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in the shadow MMU - Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for adding multi generation LRU support in KVM - Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled, i.e. when the CPU has already flushed the RSB - Trace the per-CPU host save area as a VMCB pointer to improve readability and cleanup the retrieval of the SEV-ES host save area - Remove unnecessary accounting of temporary nested VMCB related allocations - Set FINAL/PAGE in the page fault error code for EPT violations if and only if the GVA is valid. If the GVA is NOT valid, there is no guest-side page table walk and so stuffing paging related metadata is nonsensical - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of emulating posted interrupt delivery to L2 - Add a lockdep assertion to detect unsafe accesses of vmcs12 structures - Harden eVMCS loading against an impossible NULL pointer deref (really truly should be impossible) - Minor SGX fix and a cleanup - Misc cleanups Generic: - Register KVM's cpuhp and syscore callbacks when enabling virtualization in hardware, as the sole purpose of said callbacks is to disable and re-enable virtualization as needed - Enable virtualization when KVM is loaded, not right before the first VM is created Together with the previous change, this simplifies a lot the logic of the callbacks, because their very existence implies virtualization is enabled - Fix a bug that results in KVM prematurely exiting to userspace for coalesced MMIO/PIO in many cases, clean up the related code, and add a testcase - Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_ the gpa+len crosses a page boundary, which thankfully is guaranteed to not happen in the current code base. Add WARNs in more helpers that read/write guest memory to detect similar bugs Selftests: - Fix a goof that caused some Hyper-V tests to be skipped when run on bare metal, i.e. NOT in a VM - Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest - Explicitly include one-off assets in .gitignore.

Misc cleanups: - Convert devm_cxl_add_root() to return using ERR_CAST() - cxl_test use dev_is_platform() instead of open coding - Remove duplicate include of header core.h in core/cdat.c - use scoped resource management to drop put_device() for cxl_port - Use scoped_guard to drop device_lock() for cxl_port - Refactor __devm_cxl_add_port() to drop gotos - Rename cxl_setup_parent_dport to cxl_dport_init_aer and cxl_dport_map_regs() to cxl_dport_map_ras() - Refactor cxl_dport_init_aer() to be more concise - Remove duplicate host_bridge->native_aer checking in cxl_dport_init_ras_reporting() - Fix comment for cxl_query_cmd()" * tag 'cxl-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (21 commits) cxl: Add documentation to explain the shared link bandwidth calculation cxl: Calculate region bandwidth of targets with shared upstream link cxl: Preserve the CDAT access_coordinate for an endpoint cxl: Fix comment regarding cxl_query_cmd() return data cxl: Convert cxl_internal_send_cmd() to use 'struct cxl_mailbox' as input cxl: Move mailbox related bits to the same context cxl: move cxl headers to new include/cxl/ directory cxl/region: Remove lock from memory notifier callback cxl/pci: simplify the check of mem_enabled in cxl_hdm_decode_init() cxl/pci: Check Mem_info_valid bit for each applicable DVSEC cxl/pci: Remove duplicated implementation of waiting for memory_info_valid cxl/pci: Fix to record only non-zero ranges cxl/pci: Remove duplicate host_bridge->native_aer checking cxl/pci: cxl_dport_map_rch_aer() cleanup cxl/pci: Rename cxl_setup_parent_dport() and cxl_dport_map_regs() cxl/port: Refactor __devm_cxl_add_port() to drop goto pattern cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port cxl/port: Use __free() to drop put_device() for cxl_port cxl: Remove duplicate included header file core.h tools/testing/cxl: Use dev_is_platform() ...
