2022-01-09pcmcia: fix setting of kthread task statesDominik Brodowski
We need to set TASK_INTERRUPTIBLE before calling kthread_should_stop(). Otherwise, kthread_stop() might see that the pccardd thread is still in TASK_RUNNING state and fail to wake it up. Additionally, we only need to set the state back to TASK_RUNNING if kthread_should_stop() breaks the loop.

2022-01-02pcmcia: rsrc_nonstatic: Fix a NULL pointer dereference in ↵Zhou Qingyang
nonstatic_find_mem_region() In nonstatic_find_mem_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource(). Fix this bug by adding a check of res. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_PCCARD_NONSTATIC=y show no new warnings, and our static analyzer no longer warns about this code.

2021-07-21bus: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sa1111_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

The driver was introduced in 2.6.11 in the pre-git times with commit "[PATCH] mips: vR41xx updates". However, even back then, this driver was not able to be compiled, as a number of udpates had been missing from this driver: It still provided a "->get_io_map" callback (removed for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t (removed for v2.5.72). Moreover, this driver failed to be brought and be kept up to date; e.g. it still provides '->register_callback', incompatible with a change committed for v2.6.14 in commit 7f316b033b36 ("[PATCH] pcmcia: remove socket register_callback"), and uses INIT_WORK() with three arguments which was removed in commit 65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead of context data") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> [linux@dominikbrodowski.net: rewrite commit message] Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2020-06-02powerpc: add an ioremap_phb helperChristoph Hellwig
Factor code shared between pci_64 and electra_cf into a ioremap_pbh helper that follows the normal ioremap semantics, and returns a useful __iomem pointer. Note that it opencodes __ioremap_at as we know from the callers the slab is available. Switch pci_64 to also store the result as __iomem pointer, and unmap the result using iounmap instead of force casting and using vmalloc APIs.

2020-05-21pcmcia: Use CardBus window names (PCI_CB_BRIDGE_IO_0_WINDOW etc) when freeingKrzysztof Wilczynski
Remove the loop used to free CardBus resources and replace it with a yenta_free_res() helper used to release bridge resources explicitly.

2020-03-28pcmcia: soc_common.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva
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.

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf(). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
