From 3ac251b81a41295a90c89c164f0d72ce6de651aa Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sat, 23 Mar 2013 01:12:22 +0100 Subject: journalctl: various fixes to the access check logic - Reword messages a bit - Correct check whether EACCES is in the set of errors - Don't complain if no journal files are found - allocate Set object for errors lazily since in the best case we don't need it at all. - don't consider it an error if /run/log/journal doesn't exist (because that's the usual case actually, if storage is enabled) --- src/journal/sd-journal.c | 30 +++++++++++++++++++----------- 1 file changed, 19 insertions(+), 11 deletions(-) (limited to 'src/journal/sd-journal.c') diff --git a/src/journal/sd-journal.c b/src/journal/sd-journal.c index c62ad811d..f7f1777fe 100644 --- a/src/journal/sd-journal.c +++ b/src/journal/sd-journal.c @@ -51,11 +51,17 @@ /* We return an error here only if we didn't manage to memorize the real error. */ -static int set_put_error(Set* errors, int r) { +static int set_put_error(sd_journal *j, int r) { + int k; + if (r >= 0) return r; - return set_put(errors, INT_TO_PTR(r)); + k = set_ensure_allocated(&j->errors, trivial_hash_func, trivial_compare_func); + if (k < 0) + return k; + + return set_put(j->errors, INT_TO_PTR(r)); } static void detach_location(sd_journal *j) { @@ -1248,7 +1254,7 @@ static int add_file(sd_journal *j, const char *prefix, const char *filename) { if (hashmap_size(j->files) >= JOURNAL_FILES_MAX) { log_debug("Too many open journal files, not adding %s, ignoring.", path); - return set_put_error(j->errors, -ETOOMANYREFS); + return set_put_error(j, -ETOOMANYREFS); } r = journal_file_open(path, O_RDONLY, 0, false, false, NULL, j->mmap, NULL, &f); @@ -1392,7 +1398,7 @@ static int add_directory(sd_journal *j, const char *prefix, const char *dirname) if (r < 0) { log_debug("Failed to add file %s/%s: %s", m->path, de->d_name, strerror(-r)); - r = set_put_error(j->errors, r); + r = set_put_error(j, r); if (r < 0) return r; } @@ -1471,7 +1477,7 @@ static int add_root_directory(sd_journal *j, const char *p) { if (r < 0) { log_debug("Failed to add file %s/%s: %s", m->path, de->d_name, strerror(-r)); - r = set_put_error(j->errors, r); + r = set_put_error(j, r); if (r < 0) return r; } @@ -1526,8 +1532,11 @@ static int add_search_paths(sd_journal *j) { NULSTR_FOREACH(p, search_paths) { r = add_root_directory(j, p); - if (r < 0) - return set_put_error(j->errors, r); + if (r < 0 && r != -ENOENT) { + r = set_put_error(j, r); + if (r < 0) + return r; + } } return 0; @@ -1571,8 +1580,7 @@ static sd_journal *journal_new(int flags, const char *path) { j->files = hashmap_new(string_hash_func, string_compare_func); j->directories_by_path = hashmap_new(string_hash_func, string_compare_func); j->mmap = mmap_cache_new(); - j->errors = set_new(trivial_hash_func, trivial_compare_func); - if (!j->files || !j->directories_by_path || !j->mmap || !j->errors) + if (!j->files || !j->directories_by_path || !j->mmap) goto fail; return j; @@ -1630,7 +1638,7 @@ _public_ int sd_journal_open_directory(sd_journal **ret, const char *path, int f r = add_root_directory(j, path); if (r < 0) { - set_put_error(j->errors, r); + set_put_error(j, r); goto fail; } @@ -1996,7 +2004,7 @@ static void process_inotify_event(sd_journal *j, struct inotify_event *e) { if (r < 0) { log_debug("Failed to add file %s/%s: %s", d->path, e->name, strerror(-r)); - set_put_error(j->errors, r); + set_put_error(j, r); } } else if (e->mask & (IN_DELETE|IN_MOVED_FROM|IN_UNMOUNT)) { -- cgit v1.2.3
