uapi linux/coda_psdev.h: move upc_req definition from uapi to kernel side headers

2019-08-06T16:28:28Z

[ Upstream commit f90fb3c7e2c13ae829db2274b88b845a75038b8a ] Only users of upc_req in kernel side fs/coda/psdev.c and fs/coda/upcall.c already include linux/coda_psdev.h. Suggested by Jan Harkes in https://lore.kernel.org/lkml/20150531111913.GA23377@cs.cmu.edu/ Fixes these include/uapi/linux/coda_psdev.h compilation errors in userspace: linux/coda_psdev.h:12:19: error: field `uc_chain' has incomplete type struct list_head uc_chain; ^ linux/coda_psdev.h:13:2: error: unknown type name `caddr_t' caddr_t uc_data; ^ linux/coda_psdev.h:14:2: error: unknown type name `u_short' u_short uc_flags; ^ linux/coda_psdev.h:15:2: error: unknown type name `u_short' u_short uc_inSize; /* Size is at most 5000 bytes */ ^ linux/coda_psdev.h:16:2: error: unknown type name `u_short' u_short uc_outSize; ^ linux/coda_psdev.h:17:2: error: unknown type name `u_short' u_short uc_opcode; /* copied from data to save lookup */ ^ linux/coda_psdev.h:19:2: error: unknown type name `wait_queue_head_t' wait_queue_head_t uc_sleep; /* process' wait queue */ ^ Link: http://lkml.kernel.org/r/9f99f5ce6a0563d5266e6cf7aa9585aac2cae971.1558117389.git.jaharkes@cs.cmu.edu Signed-off-by: Mikko Rapeli Signed-off-by: Jan Harkes Cc: Arnd Bergmann Cc: Colin Ian King Cc: Dan Carpenter Cc: David Howells Cc: Fabian Frederick Cc: Sam Protsenko Cc: Yann Droneaud Cc: Zhouyang Jia Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Sasha Levin

coda: Restrict coda messages to the initial user namespace

2013-02-13T14:00:53Z

Remove the slight chance that uids and gids in coda messages will be interpreted in the wrong user namespace. - Only allow processes in the initial user namespace to open the coda character device to communicate with coda filesystems. - Explicitly convert the uids in the coda header into the initial user namespace. - In coda_vattr_to_attr make kuids and kgids from the initial user namespace uids and gids in struct coda_vattr that just came from userspace. - In coda_iattr_to_vattr convert kuids and kgids into uids and gids in the intial user namespace and store them in struct coda_vattr for sending to coda userspace programs. Nothing needs to be changed with mounts as coda does not support being mounted in anything other than the initial user namespace. Cc: Jan Harkes Signed-off-by: "Eric W. Biederman"

Coda: replace BKL with mutex

2010-10-25T15:02:40Z

Replace the BKL with a mutex to protect the venus_comm structure which binds the mountpoint with the character device and holds the upcall queues. Signed-off-by: Yoshihisa Abe Signed-off-by: Jan Harkes Signed-off-by: Linus Torvalds

Coda: push BKL regions into coda_upcall()

2010-10-25T15:02:40Z

Now that shared inode state is locked using the cii->c_lock, the BKL is only used to protect the upcall queues used to communicate with the userspace cache manager. The remaining state is all local and we can push the lock further down into coda_upcall(). Signed-off-by: Yoshihisa Abe Signed-off-by: Jan Harkes Signed-off-by: Linus Torvalds

coda: fixup clash with block layer REQ_* defines

2010-08-07T16:53:13Z

CODA should not be using defines in the global name space of that nature, prefix them with CODA_. Signed-off-by: Jens Axboe

coda: move backing-dev.h kernel include inside KERNEL

2010-04-28T07:20:33Z

Otherwise we must export backing-dev.h as well, which doesn't make any sense. Signed-off-by: Jens Axboe

coda: add bdi backing to mount session

2010-04-22T10:12:40Z

This ensures that dirty data gets flushed properly. Signed-off-by: Jens Axboe
