2022-02-11gfs2: Fix gfs2_release for non-writers regressionBob Peterson1-3/+4
When a file is opened for writing, the vfs code (do_dentry_open) calls get_write_access for the inode, thus incrementing the inode's write count. That writer normally then creates a multi-block reservation for the inode (i_res) that can be re-used by other writers, which speeds up writes for applications that stupidly loop on open/write/close. When the writes are all done, the multi-block reservation should be deleted when the file is closed by the last "writer." Commit 0ec9b9ea4f83 broke that concept when it moved the call to gfs2_rs_delete before the check for FMODE_WRITE. Non-writers have no business removing the multi-block reservations of writers. In fact, if someone opens and closes the file for RO while a writer has a multi-block reservation, the RO closer will delete the reservation midway through the write, and this results in: kernel BUG at fs/gfs2/rgrp.c:677! (or thereabouts) which is: BUG_ON(rs->rs_requested); from function gfs2_rs_deltree. This patch moves the check back inside the check for FMODE_WRITE.

2022-02-11iio: buffer: Fix file related error handling in IIO_BUFFER_GET_FD_IOCTLMathias Krause1-3/+11
If we fail to copy the just created file descriptor to userland, we try to clean up by putting back 'fd' and freeing 'ib'. The code uses put_unused_fd() for the former which is wrong, as the file descriptor was already published by fd_install() which gets called internally by anon_inode_getfd(). This makes the error handling code leaving a half cleaned up file descriptor table around and a partially destructed 'file' object, allowing userland to play use-after-free tricks on us, by abusing the still usable fd and making the code operate on a dangling 'file->private_data' pointer. Instead of leaving the kernel in a partially corrupted state, don't attempt to explicitly clean up and leave this to the process exit path that'll release any still valid fds, including the one created by the previous call to anon_inode_getfd(). Simply return -EFAULT to indicate the error.

When the gadget driver hasn't been (yet) configured, and the cable is connected to a HOST, the SFTDISCON gets cleared unconditionally, so the HOST tries to enumerate it. At the host side, this can result in a stuck USB port or worse.

2022-02-11net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixupJann Horn1-29/+39
ax88179_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. I have tested that this can be used by a malicious USB device to send a bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response that contains random kernel heap data. It's probably also possible to get OOB writes from this on a little-endian system somehow - maybe by triggering skb_cow() via IP options processing -, but I haven't tested that.

2022-02-10x86/sgx: Silence softlockup detection when releasing large enclavesReinette Chatre1-0/+2
Vijay reported that the "unclobbered_vdso_oversubscribed" selftest triggers the softlockup detector. Actual SGX systems have 128GB of enclave memory or more. The "unclobbered_vdso_oversubscribed" selftest creates one enclave which consumes all of the enclave memory on the system. Tearing down such a large enclave takes around a minute, most of it in the loop where the EREMOVE instruction is applied to each individual 4k enclave page. Spending one minute in a loop triggers the softlockup detector. Add a cond_resched() to give other tasks a chance to run and placate the softlockup detector.

2022-02-10riscv: fix build with binutils 2.38Aurelien Jarno1-0/+6
From version 2.38, binutils default to ISA spec version 20191213. This means that the csr read/write (csrr*/csrw*) instructions and fence.i instruction has separated from the `I` extension, become two standalone extensions: Zicsr and Zifencei. As the kernel uses those instruction, this causes the following build failure: CC arch/riscv/kernel/vdso/vgettimeofday.o <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h: Assembler messages: <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' The fix is to specify those extensions explicitely in -march.

If a call to re-create the auxiliary device happens in a context that has already taken the RTNL lock, then the call flow that recreates auxiliary device can hang if there is another attempt to claim the RTNL lock by the auxiliary driver. To avoid this, any call to re-create auxiliary devices that comes from an source that is holding the RTNL lock (e.g. netdev notifier when interface exits a bond) should execute in a separate thread. To accomplish this, add a flag to the PF that will be evaluated in the service task and dealt with there.

Currently, the same handler is called for both a NETDEV_BONDING_INFO LAG unlink notification as for a NETDEV_UNREGISTER call. This is causing a problem though, since the netdev_notifier_info passed has a different structure depending on which event is passed. The problem manifests as a call trace from a BUG: KASAN stack-out-of-bounds error. Fix this by creating a handler specific to NETDEV_UNREGISTER that only is passed valid elements in the netdev_notifier_info struct for the NETDEV_UNREGISTER event. Also included is the removal of an unbalanced dev_put on the peer_netdev and related braces.

2022-02-10ice: fix IPIP and SIT TSO offloadJesse Brandeburg2-8/+18
The driver was avoiding offload for IPIP (at least) frames due to parsing the inner header offsets incorrectly when trying to check lengths. This length check works for VXLAN frames but fails on IPIP frames because skb_transport_offset points to the inner header in IPIP frames, which meant the subtraction of transport_header from inner_network_header returns a negative value (-20). With the code before this patch, everything continued to work, but GSO was being used to segment, causing throughputs of 1.5Gb/s per thread. After this patch, throughput is more like 10Gb/s per thread for IPIP traffic.

2022-02-10net: macb: Align the dma and coherent dma masksMarc St-Amand1-1/+1
Single page and coherent memory blocks can use different DMA masks when the macb accesses physical memory directly. The kernel is clever enough to allocate pages that fit into the requested address width. When using the ARM SMMU, the DMA mask must be the same for single pages and big coherent memory blocks. Otherwise the translation tables turn into one big mess.

2022-02-10tipc: improve size validations for received domain recordsJon Maloy2-2/+9
The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet.
