2020-02-19iommu/arm-smmu: Restore naming of driver parameter prefixWill Deacon1-2/+2
Extending the Arm SMMU driver to allow for modular builds changed KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be built from the multiple existing object files without the need to rename any source files. This inadvertently changed the name of the driver parameters, which may lead to runtime issues if bootloaders are relying on the old names for correctness (e.g. "arm-smmu.disable_bypass=0"). Although MODULE_PARAM_PREFIX can be overridden to restore the old naming for builtin parameters, only the new name is matched by modprobe and so loading the driver as a module would cause parameters specified on the kernel command line to be ignored. Instead, rename "arm_smmu_mod" to "arm_smmu". Whilst it's a bit of a bodge, this allows us to create a single module without renaming any files and makes use of the fact that underscores and hyphens can be used interchangeably in parameter names.

2020-02-19iommu/qcom: Fix bogus detach logicRobin Murphy1-16/+12
Currently, the implementation of qcom_iommu_domain_free() is guaranteed to do one of two things: WARN() and leak everything, or dereference NULL and crash. That alone is terrible, but in fact the whole idea of trying to track the liveness of a domain via the qcom_domain->iommu pointer as a sanity check is full of fundamentally flawed assumptions. Make things robust and actually functional by not trying to be quite so clever.

2020-02-19pipe: make sure to wake up everybody when the last reader/writer closesLinus Torvalds1-8/+10
Andrei Vagin reported that commit 0ddad21d3e99 ("pipe: use exclusive waits when reading or writing") broke one of the CRIU tests. He even has a trivial reproducer: #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> int main() { int p[2]; pid_t p1, p2; int status; if (pipe(p) == -1) return 1; p1 = fork(); if (p1 == 0) { close(p[1]); read(p[0], &status, sizeof(status)); return 0; } p2 = fork(); if (p2 == 0) { close(p[1]); read(p[0], &status, sizeof(status)); return 0; } sleep(1); close(p[1]); wait(&status); wait(&status); return 0; } and the problem - once he points it out - is obvious. We use these nice exclusive waits, but when the last writer goes away, it then needs to wake up _every_ reader (and conversely, the last reader disappearing needs to wake every writer, of course). In fact, when going through this, we had several small oddities around how to wake things. We did in fact wake every reader when we changed the size of the pipe buffers. But that's entirely pointless, since that just acts as a possible source of new space - no new data to read. And when we change the size of the buffer, we don't need to wake all writers even when we add space - that case acts just as if somebody made space by reading, and any writer that finds itself not filling it up entirely will wake the next one. On the other hand, on the exit path, we tried to limit the wakeups with the proper poll keys etc, which is entirely pointless, because at that point we obviously need to wake up everybody. So don't do that: just wake up everybody - but only do that if the counts changed to zero. So fix those non-IO wakeups to be more proper: space change doesn't add any new data, but it might make room for writers, so it wakes up a writer. And the actual changes to reader/writer counts should wake up everybody, since everybody is affected (ie readers will all see EOF if the writers have gone away, and writers will all get EPIPE if all readers have gone away).

Some code in HD-audio driver calls snprintf() in a loop and still expects that the return value were actually written size, while snprintf() returns the expected would-be length instead. When the given buffer limit were small, this leads to a buffer overflow. Use scnprintf() for addressing those issues. It returns the actually written size unlike snprintf().

2020-02-17tpm: Initialize crypto_id of allocated_banks to HASH_ALGO__LASTRoberto Sassu1-0/+2
chip->allocated_banks, an array of tpm_bank_info structures, contains the list of TPM algorithm IDs of allocated PCR banks. It also contains the corresponding ID of the crypto subsystem, so that users of the TPM driver can calculate a digest for a PCR extend operation. However, if there is no mapping between TPM algorithm ID and crypto ID, the crypto_id field of tpm_bank_info remains set to zero (the array is allocated and initialized with kcalloc() in tpm2_get_pcr_allocation()). Zero should not be used as value for unknown mappings, as it is a valid crypto ID (HASH_ALGO_MD4). Thus, initialize crypto_id to HASH_ALGO__LAST.

2020-02-17btrfs: don't set path->leave_spinning for truncateJosef Bacik1-2/+0
The only time we actually leave the path spinning is if we're truncating a small amount and don't actually free an extent, which is not a common occurrence. We have to set the path blocking in order to add the delayed ref anyway, so the first extent we find we set the path to blocking and stay blocking for the duration of the operation. With the upcoming file extent map stuff there will be another case that we have to have the path blocking, so just swap to blocking always. Note: this patch also fixes a warning after 28553fa992cb ("Btrfs: fix race between shrinking truncate and fiemap") got merged that inserts extent locks around truncation so the path must not leave spinning locks after btrfs_search_slot.

2020-02-15Input: cyapa - replace zero-length array with flexible-array memberGustavo A. R. Silva1-4/+4
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
