2020-07-25libmachdev: Implement S_i386_io_perm_createDamien Zammit
Now that machdev redirects the device master port, it has to implement the i386 permission RPCs on it. Message-Id: <20200725011847.186969-2-damien@zamaudio.com> Message-Id: <20200725011847.186969-3-damien@zamaudio.com>
2020-07-25libmachdev: Add resume for bootstrap serverDamien Zammit
machdev users can now pass along a port to the next translator in the bootstrap chain (bootstrap_resume_task), that they'll get from their command line set by the bootloader. machdev will then call task_resume on it as appropriate. It will also have the opportunity to get fsys_getpriv calls, and thus redirect the device master port, thus having the opportunity to expose its devices on the device master port, as if they were handled by the kernel. Message-Id: <20200725011847.186969-1-damien@zamaudio.com>
2020-07-24libmachdev: Remove deviceUser, this lib is a deviceServerDamien Zammit
libmachuser provides what we need Message-Id: <20200724132039.110421-1-damien@zamaudio.com>
2020-07-18Add new RPC server stubs for device_intr_*Samuel Thibault
* boot/boot.c (ds_device_intr_register, ds_device_intr_ack): New stubs. * devnode/devnode.c (ds_device_intr_register, ds_device_intr_ack): New stubs. * eth-multiplexer/device_impl.c (ds_device_intr_register, ds_device_intr_ack): New stubs.
2020-07-18rumpdisk: link the bd on success onlyDamien Zammit
Otherwise we would crash after an unsuccessful device_open call.
2020-07-18rumpdisk: Simplify codeDamien Zammit
There is no need to store the error only to return it.

2020-07-05pflocal: Fix referencing connection queue entries.Samuel Thibault
As asserted in connq_destroy, for each entry in the queue we are supposed to keep a reference to the socket that contains the queue. So we need to keep it when connecting and release it when accepting. * pflocal/socket.c (S_socket_connect): Do not deref the peer socket when sock_connect succeeded. (S_socket_accept): Deref the socket when the accept succeeded.
2020-07-05pflocal: support SO_SNDBUF for unconnected socketsSamuel Thibault
We can store the requested value, to be applied when we connect the sockets. * pflocal/sock.h (struct sock): Add req_write_limit field. * pflocal/sock.c (sock_create): Initialize req_write_limit field to 0. (sock_connect): Bump the write_limit of the write pipe to the req_write_limit value. (sock_shutdown): Update req_write_limit from the write_limit of the write pipe. * pflocal/socket.c (S_socket_getopt, S_socket_setopt): When write_pipe is NULL, use req_write_limit.
2020-07-05pflocal: return ENOTCONN on get/setpot(SO_SNDBUF) on unconnected socketSamuel Thibault
EPIPE would raise SIGPIPE, which applications do not expect to happen on a mere get/setsockopt. * pflocal/socket.c (S_socket_getopt, S_socket_setopt): Return ENOTCONN instead of EPIPE.
2020-06-27pflocal: Fix setsockopt(SO_SNDBUF)Samuel Thibault
* pflocal/socket.c (S_socket_setopt): Make SO_SNDBUF use write_pipe instead of read_pipe.
2020-06-27pflocal: Add support for setsockopt(SO_{RECV,SND}BUF)Samuel Thibault
Thanks Svante Signell for the initial patch. * libpipe/pipe.c (pipe_recv): Move writer wake code to... (_pipe_wake_writers): ... new function. * libpipe/pipe.h (_pipe_wake_writers): New prototype. * pflocal/sock.h (PFLOCAL_WRITE_LIMIT_MAX): New macro. * pflocal/socket.c (S_socket_setopt): Handle SO_RCVBUF and SO_SNDBUF cases.
2020-06-27pflocal: Fix crash on passing erroneous portSamuel Thibault
* pflocal/socket.c (S_socket_getopt): Read `user->sock' after checking `user'.
2020-06-27pflocal: Add support for getsockopt(SO_{RECV,SND}BUF)Svante Signell
* S_socket_getopt: Handle SO_RCVBUF and SO_SNDBUF cases.
2020-06-06TODO: drop items that were doneSamuel Thibault
TLS, sigaltstack, gdb core
2020-06-01libfshelp: destroy condition variable before freeing itSamuel Thibault

2020-06-01libdiskfs: Add missing node lock around fshelp_rlock_drop_peropen callSamuel Thibault
fshelp_rlock_drop_peropen actually needs the node to be locked for proper waiting atomicity.
2020-06-01libdiskfs: Drop spurious mutex acquisitionSamuel Thibault
diskfs_make_peropen does not need node to be locked. Worse, it could try to lock it. * libdiskfs/file-reparent.c (diskfs_S_file_reparent): Do not lock node around diskfs_make_peropen.
2020-05-28libdiskfs,libnetfs: add missing io_pathconf casesSamuel Thibault
* libdiskfs/io-pathconf.c (diskfs_S_io_pathconf): For _PC_REC_MAX_XFER_SIZE, _PC_REC_INCR_XFER_SIZE, _PC_SYMLINK_MAX, return undefined. For _PC_2_SYMLINKS, return 1. For _PC_REC_MIN_XFER_SIZE, _PC_REC_XFER_ALIGN, _PC_ALLOC_SIZE_MIN, return page size. * libnetfs/io-pathconf.c (netfs_S_io_pathconf): Likewise.
