Most of these fields are as for inotify, except: mflags The flags associated with the mark (expressed in hexadecimal). msgmax — Sets the maximum size of any message sent from one process to another and is set to 8192 bytes by default. Within a shell environment, a listing of the /proc/self/ directory produces the same contents as listing the process directory for that process. 3.3.2. /proc/bus/ This directory contains information specific to the various Many of these settings, used in conjunction with one another, are useful in preventing attacks on the system or when using the system to act as a router. Check This Out
In SELinux, this is needed to support role/domain transitions, and execve(2) is the preferred point to make such transitions because it offers better control over the initialization of the process in Why is this C++ code faster than my hand-written assembly for testing the Collatz conjecture? This is primarily used with USB and Cardbus PCI. Parsers should ignore all unrecognized optional fields. https://bbs.archlinux.org/viewtopic.php?id=158864
The default value of 3, which actually relates to 16 pages, is appropriate for most systems. For file descriptors that have no corresponding inode (e.g., file descriptors produced by epoll_create(2), eventfd(2), inotify_init(2), signalfd(2), and timerfd(2)), the entry will be a symbolic link with contents of the form For more on file system sharing with NFS, refer to Chapter 18, Network File System (NFS). 3.3.5. /proc/ide/ This directory contains information about IDE devices on the system. In order for tty devices to be used as network devices, the Linux kernel enforces line discipline on the device.
flags This is an octal number that displays the file access mode and file status flags (see open(2)). root — A link to the root directory of the process. The /proc/sys/net/ipv4/conf/ directory allows each system interface to be configured in different ways, including the use of default settings for unconfigured devices (in the /proc/sys/net/ipv4/conf/default/ subdirectory) and settings that override all Ubuntu Systemctl One then clears the PG_Referenced and ACCESSED/YOUNG bits and, after some measured time interval, once again inspects the values in the "Referenced" fields to get an idea of the change in
Note: The exec-shield file must also be set to 1 for exec-shield-randomize to be effective. Obsolete, because it does not provide information on real-time signals; use /proc/[pid]/status instead. (34) sigcatch %lu The bitmap of caught signals, displayed as a decimal number. By default, the file looks like the following: 4 2 30 The first value dictates the percentage of free space required for logging to resume, while the second value sets the http://www.linuxquestions.org/questions/linux-general-1/missing-file-proc-sys-kernel-sysrq-474575/ The idea is to make the system more secure by ensuring that certain things cannot happen, at least beyond a certain point in the boot process.
Number of pages that are shared. Systemctl Enable This file can only be altered by changing the kernel source and recompiling. The idea of a DoS attack is to bombard the targeted system with requests that generate errors and fill up disk partitions with log files or require all of the system's SMS verification, is it secure?
For epoll file descriptors (see epoll(7)), we see (since Linux 3.8) the following fields: pos: 0 flags: 02 mnt_id: 10 tfd: 9 events: 19 data: 74253d2500000009 tfd: 7 events: 19 data: look at this site The default value is 1024.

By default, this file is set to Linux, and this value can only be changed by changing the kernel source and recompiling. his comment is here rtsig-nr — Lists the current number of POSIX real-time signals queued by the kernel. In SELinux, a process can set only its own /proc/[pid]/attr/exec attribute. /proc/[pid]/attr/fscreate (since Linux 2.6.0) This file represents the attributes to assign to files created by subsequent calls to open(2), mkdir(2), Finally, if it is due to the entire system being out of memory, the allowed memory represents all allocatable resources. "centos 7" "exec-shield"
o — Shuts off the system. A listing of them may be similar to the following: dr-xr-xr-x 3 root root 0 Feb 13 01:28 1 dr-xr-xr-x 3 root root 0 Feb 13 01:28 1010 dr-xr-xr-x 3 xfs For more information on mount propagation see: Documentation/filesystems/sharedsubtree.txt in the Linux kernel source tree. /proc/[pid]/mounts (since Linux 2.4.19) This file lists all the filesystems currently mounted in the process's mount namespace http://culturahq.com/cannot-stat/cannot-stat-ath-pci-ko.html Personal Open source Business Explore Sign up Sign in Pricing Blog Support Search GitHub This repository Watch 11 Star 13 Fork 1 cryptostorm-dev/cstorm_cryptohaven.science forked from fermi-cryptostorm/fermi-cryptostorm-git Code Issues 0 Pull
msgmni — Sets the maximum number of message queue identifiers. Systemctl Command Not Found Main Menu LQ Calendar LQ Rules LQ Sitemap Site FAQ View New Posts View Latest Posts Zero Reply Threads LQ Wiki Most Wanted Jeremy's Blog Report LQ Bug Syndicate Latest t — Outputs a list of processes to the console.
domainname — Configures the system domain name, such as example.com. A setting of 0 removes any delay and is not a good idea. Action must be taken immediately. 2 — Condition of the kernel is considered critical. 3 — General kernel error condition. 4 — General kernel warning condition. 5 — Kernel notice of Under this setting, the potential for memory overload is increased, but so is performance for memory intensive tasks (such as those executed by some scientific software). 2 — The kernel fails

The default is 16384. Registered line disciplines are stored in the ldiscs file, and more detailed information is available within the ldisc/ directory.
stat — The status of the process. If the kernel was built with exportfs support, the path to the target file is exposed as a file handle, via three hexadecimal fields: fhandle-bytes, fhandle-type, and f_handle. To clear the routing cache, write any value to the flush file.
