From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- fs/lockd/share.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 fs/lockd/share.h (limited to 'fs/lockd/share.h') diff --git a/fs/lockd/share.h b/fs/lockd/share.h new file mode 100644 index 000000000..a12b6c454 --- /dev/null +++ b/fs/lockd/share.h @@ -0,0 +1,39 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +/* + * DOS share management for lockd. + * + * Copyright (C) 1996, Olaf Kirch + */ + +#ifndef _LOCKD_SHARE_H +#define _LOCKD_SHARE_H + +#include + +/* Synthetic svid for lockowner lookup during share operations */ +#define LOCKD_SHARE_SVID (~(u32)0) + +/* One bit per (access, deny) pair; index = (access << 2) | deny */ +#define LOCKD_FSH_BIT(a, d) BIT(((a) << 2) | (d)) + +/* + * DOS share for a specific file + */ +struct lockd_share { + struct lockd_share * s_next; /* linked list */ + struct nlm_host * s_host; /* client host */ + struct nlm_file * s_file; /* shared file */ + struct xdr_netobj s_owner; /* owner handle */ + u32 s_access; /* access mode */ + u32 s_mode; /* deny mode */ + u16 s_access_deny_bmap; /* held (access, deny) pairs */ +}; + +__be32 nlmsvc_share_file(struct nlm_host *host, struct nlm_file *file, + struct xdr_netobj *oh, u32 access, u32 mode); +__be32 nlmsvc_unshare_file(struct nlm_host *host, struct nlm_file *file, + struct xdr_netobj *oh, u32 access, u32 mode); +void nlmsvc_traverse_shares(struct nlm_host *, struct nlm_file *, + nlm_host_match_fn_t); + +#endif /* _LOCKD_SHARE_H */ -- cgit v1.3.1
