  • d3a84a8d0   affs: fix basic permission bits to actually work ... Browse Code »

    The basic permission bits (protection bits in AmigaOS) have been broken
    in Linux' AFFS - it would only set bits, but never delete them.
    Also, contrary to the documentation, the Archived bit was not handled.

    Let's fix this for good, and set the bits such that Linux and classic
    AmigaOS can coexist in the most peaceful manner.

    Also, update the documentation to represent the current state of things.

  • 487b25bc4   fs: affs: Initialize filesystem timestamp ranges ... Browse Code »

    Fill in the appropriate limits to avoid inconsistencies
    in the vfs cached inode times when timestamps are
    outside the permitted range.

    Also fix timestamp calculation to avoid overflow
    while converting from days to seconds.

  • 1751e8a6c   Rename superblock flags (MS_xyz -> SB_xyz) ... Browse Code »

    This is a pure automated search-and-replace of the internal kernel
    superblock flags.

    The s_flags are now called SB_*, with the names and the values for the
    moment mirroring the MS_* flags that they're equivalent to.

    Note how the MS_xyz flags are the ones passed to the mount system call,
    while the SB_xyz flags are what we then use in sb->s_flags.

    The script to do this was:

    # places to look in; re security/*: it generally should *not* be
    # touched (that stuff parses mount(2) arguments directly), but
    # there are two places where we really deal with superblock flags.
    FILES="drivers/mtd drivers/staging/lustre fs ipc mm \
    include/linux/fs.h include/uapi/linux/bfs_fs.h \
    security/apparmor/apparmorfs.c security/apparmor/include/lib.h"

    SED_PROG=
    for i in $SYMS; do SED_PROG="$SED_PROG -e s/MS_$i/SB_$i/g"; done

    # we want files that contain at least one of MS_...,
    # with fs/namespace.c and fs/pnode.c excluded.
    L=$(for i in $SYMS; do git grep -w -l MS_$i $FILES; done| sort|uniq|grep -v '^fs/namespace.c'|grep -v '^fs/pnode.c')

    for f in $L; do sed -i $f $SED_PROG; done

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

    work correctly.

  • 02027d42c   fs: Replace CURRENT_TIME_SEC with current_time() for inode timestamps ... Browse Code »

    CURRENT_TIME_SEC is not y2038 safe. current_time() will
    be transitioned to use 64 bit time along with vfs in a
    separate patch.
    There is no plan to transistion CURRENT_TIME_SEC to use
    y2038 safe time interfaces.

    current_time() will also be extended to use superblock
    range checking parameters when range checking is introduced.

    This works because alloc_super() fills in the the s_time_gran
    in super block to NSEC_PER_SEC.

  • db39c1672   fs:affs:Replace time_t with time64_t ... Browse Code »

    The affs code uses "time_t" and "get_seconds()". This will cause
    problems on 32-bit architectures in 2038 when time_t overflows.
    This patch replaces them with "time64_t" and
    "ktime_get_real_seconds()". This patch introduces expensive 64-bit
    divsion in "secs_to_datestamp()", considering this function is not
    called so often, the cost should be acceptable.

  • 8ca577223   affs: add mount option to avoid filename truncates ... Browse Code »

    Normal behavior for filenames exceeding specific filesystem limits is to
    refuse operation.

    AFFS standard name length being only 30 characters against 255 for usual
    Linux filesystems, original implementation does filename truncate by
    default with a define value AFFS_NO_TRUNCATE which can be enabled but
    needs module compilation.

    This patch adds 'nofilenametruncate' mount option so that user can
    easily activate that feature and avoid a lot of problems (eg overwrite
    files ...)

  • b67bfe0d4   hlist: drop the node parameter from iterators ... Browse Code »

    I'm not sure why, but the hlist for each entry iterators were conceived

    list_for_each_entry(pos, head, member)

    The hlist ones were greedy and wanted an extra parameter:

    hlist_for_each_entry(tpos, pos, head, member)

    Why did they need an extra pos parameter? I'm not quite sure. Not only
    they don't really need it, it also prevents the iterator from looking
    exactly like the list iterator, which is unfortunate.

    Besides the semantic patch, there was some manual work required:

    - Fix up the actual hlist iterators in linux/list.h
    - Fix up the declaration of other iterators based on the hlist ones.
    - A very small amount of places were using the 'node' parameter, this
    was modified to use 'obj->member' instead.
    - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
    properly, so those had to be fixed up manually.

    The semantic patch which is mostly the work of Peter Senna Tschudin is here:

    @@
    iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host;

    Stop the AFFS filesystem from using iget() and read_inode(). Replace
    affs_read_inode() with affs_iget(), and call that instead of iget().
    affs_iget() then uses iget_locked() directly and returns a proper error code
    instead of an inode in the event of an error.

    affs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
