This patch updates pcmcia wireless drivers so that their class devices are linked to the correct physical device. Based on an patch by Adam Belay, but adapted to a different pcmcia driver model implementation. Signed-off-by:

Move the struct client_t inside struct pcmcia_device. This means it gets proper reference counting as well. The clients list inside struct pcmcia_socket can be removed now. Signed-off-by:

BUG if the socket's list of clients is not empty on shutdown and/or removal. Signed-off-by:

Dominik Brodowski authored
All in-kernel PCMCIA devices do unregister their client in their respective ->detach() function after a REMOVAL event. So, AFAICS, the dev_list iteration should always be false. Signed-off-by:

Restructure unbind_request(): Before, unbind_request was called by cardmgr on the following occasions: a) if the CS_EVENT_CARD_INSERTION event failed b) during do_remove(), which is called on 1) when cardmgr is informed of a CS_EVENT_CARD_REMOVAL event 2) when cardmgr is informed of a CS_EVENT_EJECTION_REQUEST event, if do_check() succeeds 3) cardmgr exit (SIGINT/SIGTERM), if do_check() succeeds We can ignore a), as the user is informed of the problem anyway, and can take appropriate action then (eject the card, update config, write new driver, insert card...). b1) can be done directly, even before the userspace cardmgr is informed. This speeds up the call to ->detach(). b2) All drivers I checked were based on the assumption that a CS_EVENT_CARD_REMOVAL event is received _first_, before a call to ->detach(). Most notably, some drivers issue first a call to their release() function [which else is called during EVENT_CARD_REMOVAL] during ->detach() if it hasn't been issued before. So, it doesn't hurt if unbind is only called during the EVENT_CARD_REMOVAL step, and not during EJECTION_REQUEST. The REMOVAL step is only called anyway if EJECTION_REQUEST succeeds, and the latter can only succeed if do_check() succeeds. b3) If cardmgr exits from daemon mode, ds_release() is called. I can't see a reason why this is good behaviour, especially as cards don't need cardmgr while running, only for setup. Consequences: - call unbind_request during CARD_REMOVAL handling, even before userspace is informed. - return "0" if UNBIND_REQUEST is called from userspace. - the driver's event handler is called with CARD_REMOVAL _always_ before ->detach() is called.

Use pcmcia_dev instead of the "client" single-linked list to mark clients as stale. Signed-off-by:
-
Dominik Brodowski authored
Use a struct pcmcia_device-based approach to inform "clients" of events. It needs to be done using bus_for_each_device() so that we don't need to take the device_list spinlock. Signed-off-by:

Obtain a reference to struct pcmcia_bus_socket for each pcmcia_device. This means that pcmcia_device always holds an indirect reference to struct pcmcia_socket as well. Signed-off-by:

Switch pcmcia_bus_socket's reference counting to struct kref. Also, split the access by number into two calls, so that get_bus_socket can be used in a more generic way. Signed-off-by:

As discussed previously, my integration of ds.c and cs.c with the driver model can and will only be available under the GPL, as it's too much derived of other buses' implementation of integration with the driver model. cs_internal.h did only contain the MPL header before - I contacted Dave Hinds because of this, and as far as he can tell, it was just an oversight that this was not marked as dual-licensed as the other files are.

Move pcmcia_{de,}register_client() from cs.c to ds.c, and remove the unused pcmcia_get_{first,next}_client() calls -- they would be an unnecessary hassle to deal with in the next patches. Signed-off-by: -

Remove the internal driver use_count in ds.c, as the reference counting is done in the module core anyways, and that reference count is available for cardmgr's usage by a call to module_refcount. And if !CONFIG_MODULE_UNLOAD, rmmod is useless anyways, so avoid that call by cardmgr at all. Signed-off-by:

Remove struct socket_bind_t by moving "dev_link_t *instance" to struct pcmcia_device, and transforming all users of socket_bind_t to use struct pcmcia_device instead. Also, CodingStyle updates for get_device_info and unbind_request. Signed-off-by:

Call the PCMCIA 16-bit device drivers from ds.c instead of cs.c. Also, remove the delayed handling of CS_REMOVAL events, but keep the ordering the same as it used to be due to the delay. Signed-off-by:
-
Dominik Brodowski authored
Add a new registration function to register the PCMCIA 16-bit subsystem (ds a.k.a. pcmcia) with the PCMICA core (cs a.k.a. pcmcia_core). As send_event is only called with skt->sem held, we can use that to safeguard skt->callback(), too. Note that the class_device_register() call by pccardd() is done _before_ skt->sem() is held, and the pcmcia_socket_register() doesn't hold skt->sem() as well, so there is no chance for a deadlock.

Since the big direct I/O rework do_truncate takes i_alloc_sem before calling into ->setattr. Unfortunately the other callers of ->setattr with ATTR_SIZE, most notably nfsd don't take it. The (out of tree) XFS dmapi code relies wants to release i_alloc_sem and thus gets into problems like http://oss.sgi.com/bugzilla/show_bug.cgi?id=365 This patch moves acquiring and releasing i_alloc_sem into notify_change() to make the locking behaviour consistant.

With Solar Designer <solar@openwall.com> The following patch changes the following on ELF parsing/loading code (fs/binfmt_elf): - Stronger validity checks on ELF files: treat e_phnum (program header count) < 1 as invalid treat p_filesz (file size) < 2 invalid on program header interp. case - Saner return error codes - Make sure SIGKILL is delivered on error handling Signed-off-by: -

This change still keeps the comm length at 16, but allows easier patching for local modifications, and also introduces a macro to use instead of magic 16, where sizeof(comm) is not preferable to use. Not able to use killall, pidof etc. effectively, when long process names are used for scripts. Just changing the command length from 16 to 32 breaks a.out coredump logic. Deamonise and get_task_comm helped in other places in 2.6.10. Signed-off-by:

A couple of one liners to resolve two issues that have come up regarding audit. Roger reported a problem with audit.c:audit_receive_skb which improperly negates the errno argument when netlink_ack is called. The second issue was reported by Steve on the linux-audit list, auditsc.s:audit_log_exit using %u instead of %d in the audit_log_format call. Please note, there is a mailing list available for audit discussion at https://www.redhat.com/archives/linux-audit/Signed-off-by:
